Wall Street Needs to Prepare for an AI Winter

Surely one of the silliest things that happened in tech stocks in 2024 was the sudden tumble in Nvidia Corp. shares moments after its fiscal second-quarter earnings release in August. Chief Executive Officer Jensen Huang, who otherwise walked on water this year, mentioned a minor — and resolved — blip in production of its new chip, yet investors panicked anyway.

They soon sobered up. The world, it turned out, continued to spin. But what it highlighted were the deep anxieties lurking just beneath the thin surface of optimism on artificial intelligence. The market is on high alert for signs of the peak and will react disproportionately whenever it thinks it has found one. This doesn’t bode well for 2025, when cooler heads must prevail as the progress of AI development seems almost certain to slow, possibly to a crawl.

Over the past several weeks, AI leaders have been choosing their words carefully. Google CEO Sundar Pichai, speaking at a New York Times event, said he felt the “low hanging fruit” of AI had now been picked. Expanding on the point, he told Semafor: “As we go to this next level, you need more insightful breakthroughs.”

Sam Altman, the co-founder and CEO of OpenAI, talked about how he still felt his company would reach “artificial general intelligence” but that it would “matter much less” than some observers might have previously thought. Superintelligence would be the great disruptor, he said — but it’s further away.

Behind the scenes, several reports have suggested that OpenAI is struggling to conjure the great leaps in capability that had been expected. The Microsoft-backed company’s long-awaited Sora video generation model can still be considered a hugely expensive parlor trick. Recent model releases, boasting “reasoning” capabilities and other bells and whistles, have been plainly iterative but no less expensive to create than previous models. The “wow” factor of ChatGPT is ebbing away.

Apple, meanwhile, has yet to post any evidence of the iPhone “supercycle” that some had hoped would be spurred by the introduction of Apple Intelligence. In fact, the company’s tentative AI incursions have been something of an embarrassment. Its AI-generated summaries have ranged from the comical to the severely inaccurate. With past innovations, the company told itself it would be the best if not the first. With AI it hasn’t managed either.
