Given Warren Buffett's love of good old-fashioned businesses that have proven themselves over decades, it wouldn't be surprising ifBerkshire Hathaway's (BRK.A -0.60%) (BRK.B -0.71%) chairman and CEO were wary of the euphoria over artificial intelligence (AI).

But while Buffett and his longtime vice chairman, Charlie Munger,both expressed caution about these trends at the Berkshire Hathaway annual shareholders meeting on Saturday, they also had some favorable things to say. Here's what Buffett and Munger said about AI and robotics, as well as the role that AI and robotics could play in Berkshire's portfolio going forward.

Munger has been a longtime proponent of U.S. cooperation and investment in China. Munger's investment in Chinese tech giant Alibabaand his support of Chinese electric vehicle (EV) maker BYD illustrate the growth opportunities and value that Munger believes China offers investors. "Well, if you went into BYD's factories in China you would see robotics going in at an unbelievable rate," Munger said. "So, we're going to see a lot more robotics in the world. I am personally skeptical of some of the hype that has gone into artificial intelligence. I think old-fashioned intelligence works pretty well."

Put another way, Munger sees the impact that robotics is having on manufacturing but is wary of the risks investors are taking in AI stocks. This is a stark contrast to Munger's past comments on cryptocurrency, where he called it "rat poison" and saw it as both a bad investment and useless relative to the U.S. dollar.

While Buffett shares the same hesitance about getting lost in the AI hype, there was no denying his respect for AI and its possible effects on the economy.

"There won't be anything in AI that replaces the gene. ... I'll state that unqualifiedly. It can do amazing things," said Buffett during the meeting. "Bill Gates brought me out the latest ... maybe not the latest version, but one he thought maybe I could handle. ... And it did these remarkable things, but it couldn't tell jokes."

Buffett is a big believer in human ingenuity. He often quotes American heroes like Abraham Lincoln and marvels at their decision-making ability. Although AI has a great deal of utility, it can't replace human creativity.

While Munger was more interested in the business benefits of robotics and AI, Buffett seemed to indicate that it could be yet another technology that could do remarkable things but will permanently change the human condition.

When something can do all kinds of things, I get a little bit worried because I know we won't be able to uninvent it. And we did invent for very, very good reason the atom bomb in World War II. And it was enormously important that we did so. But is it good for the next 200 years of the world, that the ability to do so has been unleashed? We didn't have a choice. But when you start something... well, Einstein said after the atom bomb, he says, 'This has changed everything in the world except how men think.' And I would say the same thing may ... not the same thing. I don't mean that. But with AI, it can change everything in the world except how men think and behave. And that's a big step to take.

There is no denying that Pandora's box has been opened for AI. A UBS study noted that OpenAI's ChatGPT reached over 100 million monthly active users (MAU) in January 2023 after launching on Nov. 30, 2022, making it the fastest application to cross the 100 million MAU mark. It then passed 1 billion monthly page visits to its website in February.

AI is having a snowball effect on search engines and consumer products. Rapid AI adoption will lead to technological improvements, and meaningful benefits, but will also make the technology more powerful than ever before.

Throughout the history of Berkshire Hathaway, Buffett has made a habit of never pretending to understand something. And for that reason, Berkshire is built around traditional businesses like railroads, utilities, and insurance companies. Until recently, the vast majority of Berkshire's public equity holdings were also these kinds of businesses. That is, until Buffett started giving more control to other members of his leadership team, who convinced him to invest in Apple (AAPL 0.81%).

As of March 31, Berkshire's Apple stake was worth a staggering $151 billion, making it roughly 46% of Berkshire's public equity portfolio. During the annual meeting, Buffett praised Apple for its relentless stock buybacks and called its products extraordinary. "Our criteria for Apple isn't any different than the other businesses we own -- it just happens to be a better business than any we own," Buffett said. Buffett said that although Berkshire has more money invested in BNSF Railway (which it owns fully) than Apple -- and that the railroad is a good business -- BNSF doesn't even come close to how good a business Apple is.

Buffett and his team are often known for being dyed-in-the-wool value investors who are hesitant to change. However, if there is a business that makes sense, Berkshire has shown it will deploy a sizable amount of capital toward a good idea.

When the iPhone changed the smartphone market in 2007, few investors, let alone Buffett himself, could have likely imagined that Apple would become Berkshire's largest public equity holding within a generation. Will the same be said for AI and robotics?

If there's one thing Buffett and his team love, it's a good business. If a company makes sense, is well-run, and has the fundamental traits Berkshire Hathaway looks for, then it could become a Buffett holding.

But don't expect Buffett to go chasing AI stocks to make a quick buck. Berkshire Hathaway could have bought Apple earlier on and made a far greater return. Instead, Berkshire waited for Apple to prove its dominance before it began loading up on the stock. The return has still been incredibly impressive.

For that reason, it would be surprising if Berkshire jumped into an AI or robotics stock in the next few years. But 5 to 10 years down the line, it would be equally unsurprising if one of the top five Berkshire Hathaway public equity holdings is an AI or robotics stock.

RITs VEX Robotics team placed 10th overall among 96 collegiate teams in the recent VEX Robotics World Championships in Dallas. Teams competing in the championship came from U.S. universities from Alaska, Oregon, and California as well as international teams from Columbia, Mexico, China, Puerto Rico, and Australia.

Two of the robots used by RIT VEX Robotics and two of the recent awards presented to the team for qualifying for the 2023 Worlds and for overall program excellence.

Closing a strong 2023 season, the team was also recognized for excellence in technical designs and the overall quality of its program.

VEX Robotics at RIT has grown significantly since it began in 2017.

Our early years, it was about building the team, understanding how we were going to run a club. We spent time recruiting people with the different disciplines needed, so we have some really talented individuals, said Stefany Ferguson, team president and a fifth-year electrical engineering major from Manchester, Conn.

Ferguson has been involved with VEX since high school, and she joined the RIT team in her first year. Placing in the top 10 this year of the championship was a milestone that Ferguson helped make happen.

VEX Robotics has several categories of competitions with K-12 competitors as well as college teams. Similar to FIRST Robotics, the program is intended to spur interest in STEM disciplines, emphasize teamwork, and encourage students to apply what they learn in classrooms to real-world projects, such as building robotic systems.

Middle and high school teams start with a kit of parts and mentors to help them build robots. At the collegiate level, teams spend the academic year designing robots, often building different parts and electronic systems in labs or machine shops. For some of the team members, the part designs are new skills being learned.

Its a great thing for a college student to know. We did a lot of 3D printing for just about every part of the robotthe gears, support towerswe also got into making silicon molds for all the wheels that we used, said Ferguson, who is completing the bachelors/masters dual-degree program in electrical engineering in RITs Kate Gleason College of Engineering.

VEX Robotics team places in top 10 at international competition - Rochester Institute of Technology

A Beverly school robotics team is ending its high school chapter with a prestigious world robotics competition prize in hand.

Wolfpack Machina, the varsity robotics team at the Waring School, recently won the FIRST Tech Challenge World Championship Inspire Award, which is the competitions top honor and recognizes excellence in robot design and teamwork. The team at the coed private middle and high school also attained the highest offensive power ranking (OPR) in the world, and won its divisional championship and the divisional Inspire Award at the competition.

The team, made up of 11 seniors and one junior, includes Thomas Davis, Alma Power, Olga Gadmer Langman, Owen Cooper, Chris Douglas, Olive Sauder, Amelia Wyler, Charlie Pound, Kaden Cassidy, Collin Keegan, Peter Hannah, and Owen Reimold.

For Inspiration and Recognition of Science and Technology, or FIRST, is an international organization for students ages 4-18 who are involved in mentor-based programs that build science, engineering, and technology skills, while promoting self-confidence, communication, and leadership. The FIRST Championship, an annual competition, was held in Houston this year.

Each year, FTC teams build and program a robot no larger than 18 in any dimension. At the competition, the robots play against each other in matches that change every year. This years challenge was to pick up cones and score by placing them on various poles.

Wolfpack Machina was one of four Massachusetts FTC teams to compete at the world competition. The team wowed the judges with a 15-page summary of its work, a strong robot performance, and an interview about their robots design, testing, code, as well as its outreach efforts and work with STEM experts.

Its outreach initiatives are an effort to bring opportunities to underserved communities, Douglas said. The team worked with Everett Public School STEM director Rupi Kaur, as well as the superintendent, to launch five FLL teams in Everett. They paid the fees and robot costs for those teams, trained the coaches, and attended practices to work directly with team members.

The team also established 35 FIRST Lego League (FLL) teams in Rwanda after Wyler moved there during her fall 2022 semester. She worked with UNESCO, the Rwanda government, and other partners to get Rwandan FLL recognized by FIRST as its own FLL region. In March, Rwanda held its first FLL Championship, which Wyler organized. There were over 700 attendees, including several cabinet ministers from Rwanda and Botswana.

It would not have worked if Amelia had not moved to Rwanda to do this personally, said team coach Francis Schaeffer. This was every day, all day for a semester at least, plus lots of work when she came back to make sure that the national championship would come off.

Schaeffer, chair of the Science, Engineering, and Technology Department at Waring, founded the FTC team in 2020, three years after he helped found Warings FLL team, the Brickwolves, which qualified for the FIRST World Championship two years in a row and had the highest scoring robot game in the world in the 2019-2020 season. Almost all of the members of Wolfpack Machina were previously on the FLL team.

Winning the Inspire Award is a culmination of the outreach theyve worked on since they began working as a team, Gadmer Langman said.

Its incredibly rewarding because it wasnt even the work we put in this year. Its the work weve put in and the time we spent together for the past six years, Gadmer Langman added.

Soon, the team members will be graduating high school. Some plan to attend an engineering school or take a gap year to work on the project in Rwanda.

Its really something to watch a kid go from being 12 and figure something out that you really understand and you can teach them to them being an expert to the level where I do not understand what theyre doing anymore, Schaeffer said.

The iCub robot has an arresting gaze

It's my first time drumming along with a robot.

I'm sitting across a table from an adorable humanoid robot called the iCub. We each have our own stick and box, and are meant to strike the box with the stick in sync with a light pattern. But of course I'm also watching the robot - and I'm aware that it's watching me.

This drumming experiment has been designed to test how the presence of a robot doing the same task affects a human's behaviour.

It's one of many experiments of human-robot interaction being carried out by the research group CONTACT (Cognitive Architecture for Collaborative Technologies) at the Italian Institute of Technology in Genoa.

Though I'm aware of the lights and the other people in the room, my gaze keeps being drawn to the iCub's heavy white eyelids.

For one thing, there's a noticeable noise when the robot blinks every few seconds. And, because this childlike robot has expressive, oversized eyes, its gaze is compelling.

Research shows humans respond better to robots that can blink

This matters because with blinking, as with other aspects of eye gaze, there's more than strictly meets the eye.

"While it is often assumed that blinking is just a reflexive physiological function associated with protective functions and ocular lubrication, it also serves an important role in reciprocal interaction," comments Helena Kiilavuori, a psychology researcher at the University of Tampere in Finland.

Human blinking conveys attention and emotion. As a means of non-verbal communication, it expresses a number of things we aren't consciously aware of, such as who should take a turn in a conversation.

Thus, it's just one of many social signals humans exchange constantly without being aware of them, yet while deriving a great deal of information and comfort from them.

So social roboticists have been studying both the physical and psychological properties of human blinking to understand why it might be useful to match it in robots.

"Due to the many important functions of blinking in human behaviour, it could be assumed that having robots blinking their eyes could significantly enhance their perceived human-likeness. This could, in turn, facilitate human-robot interaction," says Ms Kiilavuori.

Put another way, "When the robot's blinking well,people feel for your character," says David Hanson, who leads Hanson Robotics.

Making the eye and skin look natural when blinking is very challenging

Indeed, CONTACT research with 13-year-olds and adults in Italy shows that both groups simply like blinking robots more. An unblinking robot can give a person the unpleasant impression of being stared at, points out Alessandra Sciutti, who leads the CONTACT unit.

Humans also perceive robots that blink more naturally as more intelligent. And intelligence matters in situations where humans depend on robots to provide information, such as in train stations.

Despite the benefits of natural-looking blinking, integrating it into robots (apart from avatars and robots with screen displays for faces) is technically challenging.

"Blinks are one of the subtlest of human movements, so designing mechanisms that can mimic these movements require advanced technology, such as high-precision motors," Ms Kiilavuori explains. The roboticists at Engineered Arts, for example, use expensive, aerospace-grade motors as well as designing their own control electronics.

The robot made by Engineered Arts uses expensive motors to power the blink

Specifically, says Mr Hanson of Hanson Robotics, "The speed of the motors moving skin material when blinking is really challenging and making the shape of the eye look natural while blinking is happening is also challenging. As well as reducing friction between artificial eyelids and the eye surface itself."

Another issue here is a trade-off between the speed and sound of motorised blinking. Francesco Rea, a senior technician at the CONTACT unit, says that in the iCub robot a quieter motor could dampen the sound of a blink. But the slower movement then makes the robot look sleepy or catlike.

Very slow blinks also risk a loss of visual information, as the iCub's camera is located behind the eyes. "In vision, missing two frames is not that big an issue," says Mr Rea. "Missing ten frames starts to be an issue."

Ms Kiilavuori adds, "Another challenge is the correct timing and duration of blinks." The different functions that blinking performs - such as how a person changes blinking speed while telling a lie - involve different eyelid dynamics as well as different emotional states.

"Any deviation from the natural and appropriate blinking times and duration, in a given context, can make the robot appear odd and disturbing," she says.

The CONTACT team use a software program that partially randomises the intervals between single and double blinking. After all, blinking fixedly wouldn't look very natural either.

Over at Disney Research, roboticists have joined forces with character animators to develop a research prototype for realistic robotic gaze. The aim is to design an expressive system of eye gaze that is easy for animators to control in order to convey subtle emotion.

With elements like motion curves of eyelids, "we can kind of isolate these individual behaviours, which makes it much easier to really concentrate on getting small aspects and small details correct," says James Kennedy, a research scientist at Disney Research.

They've patented their system of robotic sensing and control of eye gaze. This includes software for processing images taken by a camera in the robot's chest, and generating control signals for movements like opening and closing the eyelids.

Mr Kennedy says that the research remains more experimental, and isn't yet being applied in Disney's theme parks. "The goal here was to really select a single social cue that we were interested in and push it as far as we could in making lifelike believable motion and behaviourthat we felt would provide a platform for engagement with people."

Another general challenge would be getting humanoid robots to begin syncing their blinking patterns to those of humans, as humans do in conversation.

These types of challenges remain compelling to some roboticists. And, contrary to exaggerated pop culture depictions of androids that are indistinguishable from humans, blinking is one tiny example of the many complexities that still keep robotic interactions from seeming completely natural.

When trying to replicate a mechanism as tiny and sometimes underappreciated as blinking, "actually you reveal how complex this mechanism is, and then how much subtle movement there is," notes Mr Kennedy. "And that's where we have this really great opportunity for exploration and invention."
