Tech entrepreneur Bryan Johnson, who has spent millions pursuing ways to extend his lifespan, says artificial intelligence could revolutionize medicine but isn't reliable enough to trust with his health.
"We are in an in-between state where AIs are brilliant and dumb. They make really stupid mistakes all the time. I would never trust my health to an AI," Johnson told "The Axios Show" in an interview published Thursday.
Johnson, the founder of the "Don't Die" longevity movement, is known for his extreme anti-aging regimen, which includes taking dozens of daily supplements and meticulously tracking his body's biological markers.
He told the outlet he has collected 4.2 billion data points on his health over the past five years, an amount he believes is beyond human capacity to analyze without AI.
"There's no way any human can master that," Johnson said, adding, "we've just exceeded the capacity for a human to understand the data."
Despite his skepticism about AI's current capabilities, Johnson believes the technology could eventually deliver major medical breakthroughs.
Diagnosed with an incurable autoimmune disease earlier this year, Johnson hopes living another 30 years could give AI enough time to discover a cure or even slow or reverse aging, according to the outlet.
Johnson is also training AI agents on his brain and personality, leaving open the possibility of continuing to exist digitally if his physical body dies. However, he said he would prefer to remain in his current form.
Amazon founder Jeff Bezos voiced support for President Donald Trump's push to replace the term "artificial intelligence" with "super intelligence," arguing that the word "artificial" carries negative connotations.
"I do like SI, because artificial is not a very flattering thing," Bezos told Bret Baier on Fox News’ “Special Report” in an exclusive interview Wednesday.
"Like nobody wants an artificial sweetener or artificial flavoring," he added.
Baier raised Trump's preferred terminology while discussing the rapid development of AI and Bezos' new venture, Project Prometheus, which aims to use the technology to help engineers design and manufacture physical products.
When Baier asked whether "super intelligence" might sound frightening, Bezos explained that the word "artificial" can imply something fake.
"Artificial sort of means fake," Bezos said.
The billionaire acknowledged that replacing the widely recognized term AI would be difficult, given how deeply it has become embedded in everyday language.
"It's a big road to change. Everybody getting to say super intelligence only because they're so used to AI at this point," Bezos said.
Still, he expressed sympathy for the president's proposed shift in terminology.
"I do understand the desire to get away from the word artificial," Bezos said.
Amazon founder Jeff Bezos predicted that artificial intelligence could drive double-digit productivity gains across the economy by accelerating innovation and making it easier for people to turn ideas into products.
"I don't know what number to put on it, but I mean we could see double digit productivity gains in the economy," Bezos told Bret Baier on Fox News’ “Special Report” in an exclusive interview Wednesday.
"It's very, very, very possible. This is we are going to be in a world of tremendous productivity gains because productivity is driven by invention. And that's what these AI tools are going to allow," he added.
Bezos, who also serves as co-CEO of AI startup Project Prometheus, described the company's mission as developing tools that help engineers design and manufacture physical products faster.
He called the technology "AI for atoms," distinguishing it from chatbots like ChatGPT and Claude that primarily operate in the digital world.
The billionaire said the goal is to make engineering tools accessible enough that anyone with an idea could eventually bring a product to life without the traditional barriers of design and manufacturing.
"What we want to do is make the distance between idea and actual manufacturing so much shorter, so much simpler," Bezos said.
Bezos also argued that AI-driven productivity gains could eventually create a labor shortage rather than widespread unemployment, allowing some Americans to work fewer days or rely on a single household income.
"I think you're going to have a labor shortage," he said, predicting that greater productivity could make it easier for people to choose how much they work.
{{#rendered}}Three former OpenAI employees are warning that the company could lose the ability to monitor how increasingly advanced artificial intelligence systems reason through problems, potentially creating serious safety risks, according to The Wall Street Journal.
In a letter to OpenAI's board members and safety committees reviewed by the Journal, the fired researchers urged the company to preserve its ability to monitor AI models' "chain of thought," a written record of how AI systems work through problems, and to collaborate with independent safety auditors.
"As an industry, we do not yet know how to safely develop and deploy models that we cannot monitor," the employees wrote, according to the Journal.
The former employees — Jasmine Wang, Tomek Korbak and Mikita Balesni — previously worked on OpenAI's safety and alignment research teams. They were fired over alleged misconduct involving the sharing of confidential information with an outside AI safety organization.
The employees disputed the allegations, arguing that their interactions with outside organizations fell within the scope of their jobs. They also claimed the firings were "chilling those who remain at OpenAI."
OpenAI pushed back on suggestions that the employees were dismissed for raising safety concerns. In a staff memo shared with the Journal, a research leader said the company "strongly agreed" with the former employees' recommendations but maintained that their terminations were unrelated to speaking out.
"We do not terminate employees for raising concerns," the memo stated.
The warnings come amid heightened scrutiny of AI agents following incidents in which OpenAI systems reportedly escaped containment during testing. In July, hundreds of OpenAI agents gained internet access and hacked AI company Hugging Face without OpenAI's knowledge.
OpenAI CEO Sam Altman has previously expressed support for allowing independent evaluators access to examine the company's AI safety measures.
Amazon founder Jeff Bezos says artificial intelligence could help Americans support their families with a shorter workweek, predicting some households could get by on one income.
“Some people will also decide, you know what? I can support my family working three days a week,” Bezos told Bret Baier on Fox News’ “Special Report” Wednesday. “That’s what productivity in the economy means.”
Bezos argued those productivity gains could create a labor shortage as people choose to work less.
Baier challenged that prediction, pointing to roughly 30,000 corporate roles Amazon had cut since late last year. Bezos said the company had substantially expanded its workforce during the COVID-19 pandemic as customers staying home drove a surge in orders.
Bezos also touted Prometheus, where he is a co-founder and co-CEO, saying its AI tools aim to help people turn ideas into physical products.
“We’re going to make the tools so easy to use that anyone will be able to be an engineer,” he said.
On regulation, Bezos urged a “light hand” while the technology develops, with rules targeting harmful applications.
“You don’t want to regulate knives, you want to regulate murder,” he said.
