Tech stocks today: CEOs call for pacing AI, as Nvidia CEO says extinction fears are made up

Tech stocks fell in early trading on Tuesday, as the AI industry continues to grapple with warnings that the technology could eventually harm humans. The Nasdaq (^IXIC) fell roughly 0.2%.The episode began last week when an Anthropic researcher announced he was leaving the company on X, saying he didn't feel the company was doing enough to keep AI in check.Anthropic Alignment Science Lead Evan Hubinger responded to the post, saying the former Anthropic worker is correct and that he believes there is a greater-than-10 % chance that the technology could "kill all humans."On Saturday, Anthropic CEO Dario Amodei posted an essay responding to the posts, calling on AI companies to slow the pace of frontier AI development. OpenAI CEO Sam Altman agreed.But on Monday's All In podcast, Nvidia CEO Jensen Huang said that the fears of an AI doomsday scenario are simply made up.The various announcements raised questions about whether the AI buildout will continue at its breakneck pace, or if slowing frontier AI models could cut into it.
