Hours after returning to the White House, President Donald Trump made a symbolic mark on the future of artificial intelligence by repealing former President Joe Biden’s guardrails for the fast-developing technology.

But what comes next from Trump and how it will diverge from how his predecessor sought to safeguard AI technology remains unclear. The new administration didn’t respond to requests for comment about the repealed Biden policy and even some of Trump’s most enthusiastic tech industry supporters aren’t so sure.

“I think that the previous order had a lot in it,” said Alexandr Wang, the CEO of AI company Scale, describing Biden’s 2023 executive order on AI as overly lengthy but declining to name what about it was harmful. “It’s hard to comment on each individual piece of it. There’s certainly some parts of it that we strongly agree with.”

Much of Biden’s order set in motion a sprint across government agencies to study AI’s impact on everything from cybersecurity risks to its effects on education, workplaces and public benefits. That work is done.

“The reports have been written and the recommendations generated, and they’re available for everyone to build on,” said Alexandra Reeve Givens, CEO of the nonprofit Center for Democracy & Technology.

MrBeast not yet in bidding for TikTok

Jimmy Donaldson — better known online as MrBeast — isn’t in the TikTok bidding race just yet, according to a representative for the YouTube star.

Donaldson stirred interest in a Jan. 13 post on X saying he’d “buy TikTok so it doesn’t get banned.” The next day, Donaldson added, “Unironically I’ve had so many billionaires reach out to me since I tweeted this, let’s see if we can pull this off.”

That seemed all the more certain this week when Donaldson was named in reports related to an investor group looking to buy the TikTok’s U.S. operations in an all-cash offer, led by Recruiter.com Ventures founder and CEO Jesse Tinsley. A Monday post on X from Tinsley and a Tuesday announcement from Paul Hastings LLP, a law firm that says it’s advising the group, both identified MrBeast as being part of this effort.

But, contrary to Tuesday night reports, MrBeast spokesperson Matthew Hiltzik said Donaldson hasn’t officially joined any bids. Beyond the question of whether Donaldson will be involved, how successful this group’s offer will be has yet to be seen, and a dollar amount for its offer is still unknown.

Japan Airlines expands SD-Tokyo service

Japan Airlines, which nearly four years ago resumed its nonstop service out of San Diego, announced this week that it will be expanding the flight’s frequency to seven days a week for the summer season.

The new daily service will start March 30 and continue through Oct. 25. The flight now operates four days a week.

The airline cited high demand for the change.

The nonstop flight, which has proved popular for both business and leisure travelers, made its debut in 2012.

In its news release, the airline states that it has no announcements on flight schedules beyond Oct. 25 and that those will come later.
