For more than two decades, users have turned to search engines like Google, typed in a query, and received a familiar list of 10 blue links—the gateway to the wider web. Ranking high on that list, through search engine optimization (SEO), has become a $200 billion business.
But in the past two years, search has changed. Companies are now synthesizing and summarizing results into AI-generated answers that elimin

The sky is about to get a lot clearer.

More and more, expensive and time-consuming fixes to minor issues of screen realism have become the work of statistical data renderings—the visual or aural products of generative artificial intelligence.

California Democrat Rep. Sam Liccardo, a freshman congressman who represents Silicon Valley, said he’s surprised the first piece of legislation he’s sponsoring takes aim at President Donald Trump’s meme coin.
“That wasn’t my plan when I ran for office, I can assure you,” said Liccardo, the former mayor of San Jose.

President Donald Trump vowed to fight government abuse and introduce more transparency, a stance that might align him with a little-known agency charged with watching over the U.S.’s powerful spying programs. Lately it’s investigated and critiqued the intelligence community’s secret terrorist watchlist, its fight against domestic extremism, and its warrantless searching of Americans’ emails. The agency, the Privacy and Civil Liberties Oversight Board, is also central to a hard-won agree
