Why Beijing Stands to Gain from Elon Musks Visit – The New York Times

Just days after Secretary of State Antony Blinken traveled to Beijing and warned China about unfair trade practices, Elon Musk landed in the Chinese capital. The Tesla bosss meeting with Chinas No. 2 official may have paid off: Musk reportedly cleared two obstacles to introducing a fully autonomous driving system in the worlds biggest car market.

The split screen again reveals the gap between Western diplomacy and corporate imperatives. Tesla has to stay committed to China even as it faces big headwinds a conundrum that other multinationals also face, and one that Beijing is eager to exploit.

Musk is betting big on self-driving, and China is key. Tesla last week reported its worst quarter in two years as a price war hurts profit. Tesla shares have plummeted (though theyve rebounded in recent days, and are up more than 8 percent in premarket trading) amid plans for big layoffs.

Musk has tried to reassure the market by pushing ahead with a low-cost model. Fully autonomous driving is also crucial. Musk told analysts last week that if investors dont believe Tesla would solve the technological challenge that is autonomous driving, I think they should not be an investor in the company.

The carmaker faces challenges in its second biggest market. Heavily subsidized Chinese rivals are eating into sales, led by the Warren Buffett-backed BYD, which is vying with Tesla for the crown of worlds biggest E.V. maker.

Teslas are banned from many Chinese government sites because of concern about what data the American company collects. President Bidens move to declare Chinese E.V.s a security threat probably wont have made it any easier for Tesla in China.

Why Beijing Stands to Gain from Elon Musks Visit - The New York Times

Elon Musk says any company that isn’t spending $10 billion on AI this year like Tesla won’t be able to compete – Fortune

Elon Musk has a message for Americas business leaderseither prepare yourself for the AI revolution or start writing your corporate obituary.

At a juncture in time when Teslas CEO is cutting back on investments into new vehicle capacity, he is spending $10 billion this year alone to bulk up on AI training and inference, and position Tesla at the forefront of the industry for real-life applications outside of generative AI.

Any company not spending at this level, and doing so efficiently, cannot compete, he posted on X Sunday.

Spending on AI inference would primarily be targeted at his range of cars, a possible indication that he is preparing the ground for the next generation of his custom-designed Full Self-Driving (FSD) computer known as HW5.

The distinction between training and inference is important since close observers will know Musk is currently working on another major AI project, his humanoid robot dubbed Optimus after the 1980s cartoon vehicle that transformed into a sentient robot.

This bold and risky pivot toward AIand by implication away from his previous focus on a tenfold increase in car sales to 20 million EVs annuallydefinitively answers theperennial questionwhether Tesla is an automaker or a tech company in favor of the latter.

Any typical auto executive would have long since invested in rejuvenating one of the oldest product ranges in the auto industry. For example, Teslas EV archrival, BYD, is pumping out one new model after another across its portfolio of brands with the help of its small army of90,000 vehicle engineers.

Musk however seems to view his cars more as an iPhone on wheels, a premium device for delivering high-margin software, that can be sold at lower profit since revenue will be recouped by offering services around the vehicle.

For the moment, that approach has not worked. Tesla has found itself forced torepeatedly cut pricesto stimulate enough demandto keep his factories humming. Musk even recently resorted to slashing the price of his FSD softwareby a third.

Only 18 months ago, the idea of Tesla struggling to find customers seemed ludicrous, to borrow a favorite adjective of Musk. Yet Chinas new generation of EV rivals are in aclass of their ownwhen it comes to value for money, and his own personal brand has beentarnished.

Musks latest answer has been to pivot away from a direct match-up car for car, and instead attempt to be the first global company to carve out a stake of the future market for autonomous ride-hailing networks.

While it is true the Tesla CEO predicted year after year that his cars would be able to drive entirely on their own without supervision, only to fail each and every time, his new FSD software v12 is apotential game changer. Unlike all his previous attempts, it runs entirely on AI without resorting to hard-coded commands, and initial customer feedback has been positive.

Emboldened by the success, Musk has quickly snatched up every AI chip he can find.

In the first quarter alone, Tesla spent $1 billion more than doubling its compute capacity to the equivalent of 35,000 Nvidia H200 chips, the benchmark for AI processing. Last week Musk promised this figure would hit 85,000 by theend of the year.

Musk hopes none of his direct competitors will take him up on his advice and Tesla will be able to be the first to solve unsupervised self-driving at scale and beat out Waymo to the lucrative business of licensing out his autonomous technology to rivals.

A key step in that direction is proving v12 is just as capable abroad as it is in the United States, where its software was trained.

On Monday he managed toclinch a dealthat could see FSD finally gain approval in China. To placate demands from Beijing, Musk partnered with local internet search giant Baidu, itself a major contender in self-driving cars, to license the latters mapping and navigation software.

Musk winning FSD approval in the key China market is a watershed moment for the Tesla story in our view, wrote Wedbush senior tech analyst Dan Ives on Monday. Shares in Tesla are expected to surge over 9% when trading begins.

In the meantime, the Tesla community increasingly suspects Tesla has cancelled its$25,000 low-cost EVinall but name, and could instead launch ahatchback versionof its Model 3 sedan that can be manufactured using existing production lines. That means Musk doesnt have to splash out even more cash to build new capacity.

Investors likebillionaire Ron Baronhave hailed the decision, since Tesla is alreadly saddled with too many factories and could easily close one. Musks company can currently build 3 million cars this year across its four vehicle manufacturing plants, according to Baron, but in all likelihood will not sell more than 2 million this year.

Elon Musk’s Starlink satellite internet terminals keep working in places they’re not supposed to – Quartz

Starlink satellite internet terminals are reportedly still operating in unlicensed places, despite the companys warning last month that the service would be shut down by May 1 in those areas.

Wegovy and Ozempic: Are we ready for weight loss drugs?

A resident of Al-Fashir in North Darfur, Sudan was able to conduct an interview with Bloomberg using one on Wednesday.

Im currently talking to you through the Starlink connection, its the only way of connecting between people, especially those who fled the war, he told Bloomberg, referring to the civil war between the Sudanese Armed Forces (SAF) and the paramilitary Rapid Support Forces (RSF).

The Starlink shutdown warnings came after Bloomberg and the Wall Street Journal reported of its unauthorized use in nations including Russia, Yemen, and Venezuela. Starlink accountholders received emails from Starlink about the impending shutdown in those unlicensed areas, Bloomberg and the Journal reported. If you are operating your Starlink Kit in an area other than areas designated as available on the Starlink Availability Map, we would like to remind you that this is in violation of the Starlink terms, the email read, adding that those users would be unable to connect to the internet starting on April 30th.

An online poll found that of almost 100 Starlink customers in South Africa, 73% could still use the service after the shutdown date, Bloomberg reported, adding that some Starlink customers in Sudan were also able to access the service.

Starlink users were told in an email the service was only intended for temporary travel and transit, in unlicensed places, rather than for permanent use. It added that users who have accessed Starlink outside of authorized places for over two months should change your account country or return to the country in which your service was ordered, or else their service would be cut off, Bloomberg reported.

The notice also comes as, SpaceX is reportedly close to a licensing deal to provide Starlink in Yemen. SpaceX, Starlinks parent company, did not immediately respond to a request for comment.

Humanitarian organizations in Sudan told Bloomberg they have asked that Starlinks services not be cut off in the country amid the war.

We have contacted Starlink in order to consider the situation in Sudan and not cut services, Hadreen, a local charity, told Bloomberg. The majority of the emergency rooms, the public kitchens and thousands of people are using Starlink internet to survive.

Elon Musk Reaches Deals in China on Self-Driving Teslas – The New York Times

Tesla has concluded a series of arrangements with regulators and a Chinese artificial intelligence company during a quick trip to Beijing on Sunday and Monday by Elon Musk, the carmakers chief executive, potentially clearing the way for the company to offer its most advanced self-driving software on cars in China.

Tesla had faced a couple of hurdles to offering the latest level of autonomous driving, which it calls supervised Full Self-Driving. It has needed approval from Chinese regulators, who questioned whether the company took adequate precautions to protect data. And it has needed access to extremely high-resolution maps across the country.

The timing of Mr. Musks trip was significant. He arrived in China days after he identified self-driving technology and artificial intelligence as critical to Teslas future. Tesla is not just a car company, Mr. Musk told investors last week, saying, We should be thought of as an A.I. robotics company.

Approval of the technology in China would give Mr. Musk a much-needed win after regulators in the United States issued a harsh assessment of the systems safety and performance in a report released on Friday.

Mr. Musk flew on his private jet to Beijing on Sunday morning and met almost immediately with Premier Li Qiang, Chinas No. 2 official after Xi Jinping. Mr. Li is a longtime ally of Mr. Musk who, when he served as Communist Party secretary in Shanghai, helped clear the way for Teslas construction there of what is now the companys largest car assembly plant.

The government-linked China Association of Automobile Manufacturers later announced that Tesla and five Chinese automakers had obtained approval from authorities and the association for their data security precautions on dozens of car models. The rules bar automakers in China from using software that would identify the face of anyone outside his or her vehicle, and include many other restrictions. Self-driving systems use cameras to guide vehicles.

Elon Musk goes ‘absolutely hard core’ in another round of Tesla layoffs – The Verge

Barely two weeks after initiating layoffs for at least 14,000 staffers, Tesla is now reportedly laying off hundreds more including senior executives and the majority of its Supercharging team.

According to an email first reported by The Information and then Electrek, the automakers senior director of EV charging Rebecca Tinucci is leaving the company on Tuesday, alongside most of the 500-person team she oversaw. Teslas head of the new vehicles program, Daniel Ho, is also out along with his team. These cuts come in addition to the recent 10 percent workforce reduction and Musks email leaves room for more.

In the email sent to executives last night, Musk said he wants Tesla to be absolutely hard core about the cuts, and that staffers working under executives who dont obviously pass the excellent, necessary and trustworthy test would also be out of a job. While the full scale of these new layoffs is unclear, Bloomberg previously reported that Teslas total headcount reduction that began earlier this month could end up being as high as 20 percent of its workforce, or well in excess of 20,000 employees.

Tinucci was notably responsible for the rollout of Teslas Supercharger network during her six years at the company, including efforts to get other companies to adopt the North American Charging Standard (NACS) developed by Tesla. In his email, Musk says Tesla will still build new Superchargers and complete those already under construction.

Others impacted by the new layoffs include Daniel Ho, a ten-year Tesla veteran who served as director of vehicle programs and new product initiatives, and as program manager for the Model S, 3, and Y vehicles. Most of the public policy team led by former head of policy and business development Rohan Patel (who left the company during the previous wave of layoffs) are also being let go.

Tesla layoffs shake confidence in the EV-charging future – E&E News by POLITICO

For the last dozen years, as the prospects for Americas electric vehicles have veered between optimism and doom, industry insiders could always count on one rock-solid, reliable thing: Teslas charging network.

Late Monday, that all changed.

In a single stroke, CEO Elon Musk called his companys vaunted charging reliability into question when he laid off most or all of Teslas Supercharger team, the people who made Tesla the envy of the EV industry. The network they built is bigger, faster, smarter and more reliable than any other companys and has become the linchpin of the auto industrys plan to persuade millions of Americans to buy EVs and turn the tide on climate change.

It feels like the rug just got pulled out from under a lot of the industry alignment that has been built in the last 12 months, said Matt Teske, an industry veteran and CEO of Chargeway, an EV-charging software platform. And leaves us on shaky ground.

The abrupt decision left the ever-widening ecosystem of people who rely on Tesla drivers, automakers, suppliers, electric utilities and policymakers suddenly in the lurch, as emails to longtime Tesla contacts bounced and the most respected team in the industry all but ceased to exist.

This targeted layoff is Musks latest response to a sharp downturn in Teslas prospects as its cars become less popular. Last week, while reporting lower earnings, Musk said that the automaker would shed more than 10 percent of its global workforce of 140,000.

We need to be absolutely hardcore about headcount and cost reduction, Musk said in an email to Tesla staff on Monday, reported first by The Information. While past rounds of layoffs have been spread among divisions, this one lopped off hundreds of people on the EV charging team, including Rebecca Tinucci, the units head.

Suddenly, a lot of things that seemed beyond question are being nervously asked.

Whats the plan, whats the strategy, and at such a pivotal moment, why are they bailing on that entire team? asked Jonathan Katz, an EV-charging executive who was part of Teslas charging unit for five years ending in 2020.

Will Tesla drivers and now other EV drivers be able to continue to rely on the network that was one of the main perks about buying a Tesla? Will the automakers who bet their future EVs on Teslas charging stations and technology still have a reliable partner? Will Tesla be there to guide an industrywide transition to the technology that it invented? And will Tesla continue to participate in the federal build-out of charging stations an effort that, until this week, it was leading?

Musk on Tuesday addressed the uncertainty in a post on X, the social media platform formerly known as Twitter and that Musk now owns, saying: Tesla still plans to grow the Supercharger network, just at a slower pace for new locations and more focus on 100% uptime and expansion of existing locations.

The news, while startling, struck some as a canny move perhaps one that reflects the maturing EV sector, where more players are coming onto the scene and can take over the charging tasks that Tesla has, until now, managed mostly by itself.

Musk clearly looked at what needs to be done to build out the Supercharging network, and it is probably a lot less than what it took to design and plan it, said Karl Brauer, an auto analyst for the car-sales website iSeeCars.com.

However, some questioned how Tesla will carry out a slower expansion or any operations at all if the team behind it is no longer there. No one contacted for this story could name a single source in Teslas charging sector that still works there.

One of those trying to reach Teslas team Tuesday was Andres Pinter, the co-CEO of Bullet EV Charging Solutions, a company that provides electricians and other workers to build charging stations. Tesla Supercharger stations account for a quarter of its work.

The companys chief operating officer, Mark Vogel, was driving to a job in Dallas this morning when he received a call from our Tesla construction lead saying that his entire team was laid off, Pinter wrote in a Tuesday email. I have gotten email bounces from at least 20 Tesla contacts.

Its unclear to me who, if anyone, is still at Tesla who has anything to do with charging, he added in a phone interview.

Teslas sudden reversal matters because of the constancy of its charging network. Sophisticated, widespread and functioning as planned, it earned a unique and foundational role in the world of American electric vehicles.

When Tesla founded the Supercharger network 12 years ago, it realized earlier than others that a widespread and reliable web of changing stations was key to ensuring drivers would make the jump to electric cars.

The system grew out as a web of so-called Destination chargers slow chargers located at overnight locations like hotels and Superchargers, an exclusive perk meant for Tesla drivers to quickly fill batteries on the go. The charging system was designed to be tightly bound to the car itself, so drivers could set in a destination and get real-time instructions on where to charge and for how long.

Tesla reported last week in a financial filing that it has built more than 6,200 Supercharger plazas, far more than any other company. Even as layoffs began, the team was unveiling numerous new locations, from San Diego to Taiwan.

They had become such a well-oiled machine, said Teske.

To carry out that feat, Teslas Supercharger team mastered a host of behind-the-scenes skills that it did better than anyone else: pinpointing the highway interchanges where a refill is most needed, coordinating with the electric utility to learn where the power supply was strongest and persuading restaurants and malls to trust Teslas promise that building rows of Superchargers in their parking lots would bring new foot traffic and customers.

Along the way, the company also became an expert contributor in the policy arena.

Any time a state legislature, agency or public utility commission considered a change in the rules to govern the new arena of EV charging or offered money to build out a network Tesla would usually submit comments. With far more experience than any other company, their briefs carried an authority that others didnt.

Teslas charging team worked hand in hand with the companys public policy team, which has also been disbanded. The head of public policy, Rohan Patel, stepped down last week.

This nexus of the Supercharger team along with the public policy team, they worked really well together to get where we are, Teske said.

In 2022, as traditional automakers finally started delivering a substantial number of EVs to the roadways, they ran into a problem. Their drivers couldnt use Teslas chargers, because they were meant only for Teslas. And the public networks had an array of reliability problems.

Ford was the first automaker to hit on the solution. Last spring, it struck a deal with Tesla to use its 12,000 U.S. charging stations and committed to building Teslas charging technology called the North American Charging Standard, or NACS, into its future vehicles.

Other automakers followed suit in short order. By February, Teslas NACS had become the industry standard, with virtually every automaker planning to redesign their charging systems to meet Teslas specifications.

Teslas charging prominence became such that it challenged the Biden administrations plans and redefined federal policy.

The bipartisan infrastructure law, passed by Congress in 2021, allocated $7.5 billion for a charging network. Its early rules called for those stations to be built using the public standard at the time, called the Combined Charging System.

But when automakers piled into Teslas camp, the Biden administration was forced to scramble, opening its rules to changes so stations would qualify if they offered both systems.

With Teslas charging expertise now disbanded, the players who relied on it face uncertain circumstances.

One example is state departments of transportation, which are now in the process of determining what companies will win awards to build charging stations under the National Electric Vehicle Infrastructure (NEVI) program. The $5 billion, five-year arm of the bipartisan infrastructure law aims to build a backbone of charging stations along highways.

Tesla, already a winner of roughly 14 percent of these awards, is poised to pick up more in states that have announced tentative winners.

But with Tesla removing itself from the market, your decision is more complicated all the sudden, said Loren McDonald, the founder of EVAdoption, an EV-charging data platform that tracks NEVI. With Tesla newly bereft of staff, she said, What do you do?

Even more consequential choices might face automakers, which are planning to install Teslas NACS technology in their cars starting next year.

In theory, Teslas competitors can operate the new charging platform without Teslas help. But in practice, Tesla is or was the one with the most expertise, and without it, the new EV charging systems could be less reliable.

It leaves a lot of questions: Are these automakers still going to get the level of support they were promised? asked Katz, the former Tesla charging employee.

Automakers, for their part, said their plans to move to Teslas NACS are still underway.

A spokesperson for Ford, Martin Gnsberg, said, plans for our customers do not change. A spokesperson for General Motors, Darryll Harrison, echoed that sentiment and added, we are continuing to monitor the situation.

Whatever the consequences, the startling speed of the turnaround shows that EV charging once the steadiest part of Teslas business is now starting to look like another area subject to Musks hair-trigger impulses.

It was urgent acceleration and growth, said Pinter, the head of Bullet EV Charging Solutions, whose workers were left in the lurch Tuesday. And now, nothing.

Supreme Court rejects Elon Musk’s efforts to get rid of his Twitter sitter – The Verge

Musk has been required to receive approval from his so-called Twitter sitter after signing a consent decree with the SEC in 2018 in response to his tweets about taking Tesla private, in which he falsely stated to have funding secured.

But ever since agreeing to the settlement,Musk hasbeen tryingto wrigglehis way out of the consent decree that he have a lawyer review posts that could have a material impact on Tesla before publishing them. Moreover, if the Twitter sitter does indeed exist, no one has stepped forward to claim the job. Tesla has declined to identify the person. AndBloombergs Dana Hull, who has been investigating the Twitter sitter for years, has yet to turn up a name.

The Twitter sitter lives on

Last year, a federal appeals court rejectedMusks bid to toss or modify the settlement. Musks lawyers appealed the decision to the Supreme Court, arguing it violated their clients free speech rights. But today, the court declined to take up the case, leaving the lower courts ruling in place.

The federal appeals court found that the SEC has only investigated three of his past tweets: the infamous 2018 funding secured tweet that subsequently resulted in the consent decree, a $40 million fine, and Musk losing the chairmanship of Tesla; and two other tweets, one that contained misleading information about Teslas vehicle production and the other regarding a poll proposing Musk sell 10 percent of his Tesla stock.

Elon Musk’s Tesla layoffs slam everyone from interns to executives – Quartz

Elon Musks drive to slash costs at Tesla is hitting almost every corner of the company, from senior-level executives to summer interns just weeks away from employment.

Wegovy and Ozempic: Are we ready for weight loss drugs?

Joshua Schreiber, a student at Miami University, was set to start his summer internship with Tesla in just three weeks and said he already spent thousands of dollars on housing. Now, hes looking for a new gig.

At 8:46am, I opened a Tesla email for flight info, he wrote on LinkedIn on Wednesday, in a post first reported by Bloomberg. By 11:25am, my internship offer was gone.

The unexpected cancellation comes at a rough time for college students looking for summer jobs to occupy their time, make some cash if theyre paid programs and get valuable experience. Most universities are wrapping up the spring semester and many applications across fields have already closed, making nabbing a new job difficult.

Teslas decision to rescind summer internships has affected students looking to learn and work with teams across the company, from megapack production and human resources to corporate sustainability. Diana Rosenberg, who works in battery supply at Tesla, asked her LinkedIn network to help one intern-to-be find a new summer position to support their career.

Please make our loss your gain! Rosenberg wrote.

Musk on April 15 announced that Tesla would move to cut more than 10% of the companys 140,000 people global employees, including its marketing team, as part of cost-cutting measures. Musk had reportedly pushed to lay off about 20% of the company an amount, he reasoned, that would match Teslas sales decline between the fourth quarter of 2023 and the first quarter of 2024.

As we prepare the company for our next phase of growth, it is extremely important to look at every aspect of the company for cost reductions and increasing productivity, Musk told workers in a memo last month, before announcing the imminent layoffs. There is nothing I hate more, but it must be done.

Its unclear how much money Tesla will save from revoking intern offers, but its unlikely to be a lot. Some internships are for unpaid positions, while paid interns usually make $18 to $28 per hour, according to Glassdoor. Over 3,000 students are hired for internship and apprenticeships each year, according to Teslas 2022 impact report.

Earlier this week, Tesla laid off the majority of its 500-person Supercharger division. Rebecca Tinucci, a six-year veteran of the company overseeing the division, has also left Tesla. At least five other high-profile executives have either already resigned or plan to later this year, including Tesla leaders overseeing investor relations, human resources, and public policy.

Behind all of these cuts is Musks move into wartime CEO mode to reassure investors skeptical of his promises and Teslas Full Self-Driving technology. Also on the table is Musks $47 billion pay package, which will be voted on by shareholders over the summer. Several stockholders, including Teslas biggest retail shareholder, have expressed their opposition to reapproving the package, which was struck down by a judge in Delaware earlier this year.

The rest is here:

The Science of Frozen Heads: How the First Cryonic Brains Will Rise Again – Popular Mechanics

In December 2014, Dr. Stephen Coles, a UCLA professor who studied aging, passed away from pancreatic cancer. While for many years Coles had made his home in Los Angeles, he chose to enter hospice care in Scottsdale, Arizona. That way, he could be close to the team of doctors who would

Once Coles was pronounced dead, that team arrived at his bedside. They restored his breathing and blood circulation with a heart-lung resuscitator, also known as a thumpera mechanical device used in emergency medicine to perform CPRand injected his body with anticoagulants to keep the blood flowing. All of this was done to protect the brain from damage that can occur after too long without oxygen. Next, the body was cooled in an ice water bath, the blood replaced with an organ preservation solution.

Finally, Coles body arrived at its final destination: Alcor, the nations oldest provider of cryonics, the freezing of human corpses and brains in liquid nitrogen that will one daytechnology willinglive again.

There, surgeons performed a neuroseparation, removing Coles head at the sixth cervical vertebra, and pumped cryoprotectants (medical-grade anti-freeze) into the now severed head. Then, a forensic pathologist opened the skull and removed the brain.

Coles had died around 10 a.m.; by dinner time, his brain was in a silver dewar, its thermostat set to -140 degrees Celsius.

The Patient Care Bay at Alcor holds a number of Bigfoot dewars, which are custom-designed to contain four whole-body patients and five neuropatients each. The dewar is an insulated container which consumes no electric power. Liquid nitrogen is added periodically to replace the small amount that evaporates.

Coles was Alcors 131st patient but one of its first to select brain-only cryopreservation, sometimes called neuropreservation or neurosuspension. A company announcement called Cole an unusual brain-only patient, and revealed that the unfamiliar nature of the procedure created several major challenges, with procedures being revised even as the surgery and perfusion were underway.

Ten years later, according to Emil Kendziorra, M.D., CEO of Tomorrow Bio, a German biotech firm that specializes in human cryopreservation, brain removal is not a big issue, and becoming more popular among those interested in cryonics. Storing a brain is faster, cheaper, anddespite the human taboo of decapitationpoised for a higher degree of social acceptance, Dr. Kendiziorra says, since anatomy departments and research institutions have been storing brains for years.

But what about the rest of the body? Wont future humans need their legs and arms when they wake up from their cryonic suspension?

While the brain is unique and cannot be recreated, the fundamental logic is that all the rest of the body can be recreated, Dr. Kendziorra tells Popular Mechanics. This means that by the time technology exists to cure death and reanimate the human brain, slapping together a real or virtual vessel should be a cinch.

These ideas may seem far-fetched, but Dr. Kendziorra is quick to point out that there was a time in the past when heart transplantationtaking one heart and connecting into another bodysounded pretty science fiction as well.

But as neuropreservation grows in popularity, the question remains: what will we do with all of these frozen brains in the future?

***

Dr. Kendziorra is a trained medical doctor-turned-cryonics evangelist. As a former cancer researcher, he was frustrated by the agonizingly slow pace of progress and never found it acceptable to tell a 25-year-old that they have incurable cancer and theyre going to die, he says. I think that everybody should live as long as they choose to.

Its important to point out that no human brain (or whole human for that matter) has ever been revived after death. The hope behind cryonics is that, eventually, very smart people using technology that hasnt been invented yet will figure out how to conquer death. For anyone with an untreatable diseaseor anyone who would like to live beyond their average lifespanto elongate their lives, they just need to freeze themselves, and then wait for those smart (and hopefully benevolent) people to wake us up.

Its also important to point out that freeze is the wrong word. Technically, cryonically preserved bodies arent frozen, theyre vitrified. Youve probably heard that the human body is 70 percent water; if you popped a corpse in the freezer, there would be a lot of cracking when ice crystals formed in the cells and damaged the body beyond revival. Upon thawing, the body would be mushy, thanks to the ruptured cell walls caused by cracking.

The Alcor operating theater in Scottsdale, Arizona. Here, surgeons perform initial procedures to gain access to the patients vascular system, replacing the blood with a cryoprotectant solution to prevent the formation of ice crystals during subsequent cooling.

Instead, cryopreservation involves vitrification, replacing the blood with a medical antifreeze, called cryoprotectant, then cooling the body gradually until it resembles glass.

The cost of these proceduresas well as transporting the body and storing it for untold yearsis not cheap. For full-body suspension, Tomorrow Bio charges 200,000. Thats why, although he always recommends full-body cryopreservation, Dr. Kendziorra says that, at the bargain price of 75,000, brain-only cryopreservation is an attractive option to those hoping to extend their time on Earth.

Dr. Kendziorra says he feels strongly about making cryopreservation possible at more price points, but its not just humans hoping to live forever that will benefit from increasing affordability. The field of cryonics needs an infusion of cash and research funding if it is going to maintain long-term storage facilities and figure out how to cure death. Theoretically, more bodiesor brainsin more tanks will lead to a greater investment in these endeavors by the scientific community.

Today, Alcors membership is split nearly evenly between whole-body and neuro cryopreservation. While neurosuspension is easier and less expensive, there are still some compelling reasons to consider whole-body cryopreservation.

For one thing, no one can be sure that the brain contains everything we would need to feel like ourselves upon reanimation. Without the central nervous system, the spine, the endocrine glands, and microbiome, would we recognize ourselves upon waking in the distant future?

Its a concern that led Becca Ziegler, a 23-year-old Tomorrow Bio member, to opt for whole-body preservation. From my understanding, everything that makes me me is in the brain, she says, but there are still some unknowns about consciousness and memories and how the brain interacts with the rest of the body. So I chose whole-body cryopreservation to ensure that there are no essential parts of my consciousness and memories that arent cryopreserved.

Dr. Kendziorra says that out of an abundance of caution, his company always recommends whole-body cryopreservation, unless its not within the budget of a perspective member. After all, rousing from a cryonic state hundreds of years in the future with only half of your identity would be a real disappointment. Better safe than sorry, says Dr. Kendziorra.

***

According to Dr. Kendziorra, there are currently four working theories for what future generations will do with thawed-out human brains. All of this is very speculative, he warns, but they have potential.

The first and perhaps most realistic, based on existing technology, is 3D printing.

We could 3D print all the other organs and connect the brain, Dr. Kendziorra says. This technology isnt there quite yet, but its probably not that far away anymore. Indeed, 3D organ bioprintingthe use of human cells to create three-dimensional tissueis a quickly evolving field, fueled by the hundreds of thousands of people who need organ transplants. Jennifer Lewis, a professor at Harvard Universitys Wyss Institute for Biologically Inspired Engineering, predicts the technology could be ready in a decade.

Another possibility will be the development of clones using DNA taken from brain tissue. The clone, of course, will need to be created without a brain, so that the old one can be transplanted. Since the birth of Dolly the sheep in 1996, scientists have cloned 22 animal species as well as a human embryo. Could brainless vessels be next?

Some scientists believe clones wont be necessary, and that reanimated brains could be transplanted in donor bodies, a method neurosurgeon Sergio Canavero called technically feasible, in a recent paper (published in a journal he is an editor of, it should be mentioned). After detailing how the cranial nerve and vascular system could theoretically be reconnected to the brain, the controversial scientist admitted there was lots of work still ahead, including cadaveric rehearsals, tests in brain-dead organ donors, and the development of new surgical tools. With appropriate funding, he argued, a long-held dream may finally come true.

The third way a reanimated brain could once again express itself is by being placed in an artificial body. In simpler terms, a robot body, says Dr. Kendziorra. Elon Musk thinks its possible and so does Michael S.A. Graziano, a Princeton neuroscientist. Graziano argued in a Wall Street Journal essay that uploading a mind into a robot body would take only two pieces of technology: an artificial brain and a scanning device with the ability to measure exactly how [a brains] neurons are connected to each other, to be able to copy that pattern in the artificial brain.

Then again, the robot might not even be necessary. We could reinstantiate the brain by connecting it to a computer, and all sensation inputs and outputs would be virtual, Dr. Kendziorra explains. On some abstract level, maybe theres not much a difference between real and virtual. Hes got a point; some scientists already believe were living in a simulation.

Regardless of just what future humans do with cryonically preserved brains, Dr. Kendziorra believes its going to take a long time to figure it out. Medically and technologically we are not there yet, and we will not be there for many, many decades. Its going to take a significant amount of time. And in fact, it might never work.

But if theres a reason to stay hopeful about cryonics, Dr. Kendziorra says its because the other option isnt so great either. The alternative, he laments, is death.
