Alphabet Inc. is falling amid renewed fears that the Google owner’s missteps in artificial intelligence are putting its search business at risk. 

The stock dropped as much as 4.4 per cent Monday following last week’s pause of a Google image generation feature that drew criticism over inaccurate historical depictions of race. Alphabet shed more than $70 billion from its market value.

Problems with AI tools may fuel the perception that Google is “an unreliable source for AI” and create an opening for competitors, Melius Research analyst Ben Reitzes warned in a research note. 

“We have been arguing that Search behavior is about to change - with new AI-infused features,” said Reitzes. “This ‘once in a generation’ change by itself creates opportunities for competitors, but even more if a meaningful portion of users grow concerned about Google’s hallucinations and bias.”

Last week, Google acknowledged inaccuracies in image generation depictions of people and said it’s addressing the problems. Google aims to resume the feature in the “next couple of weeks,” Demis Hassabis, head of the research division Google DeepMind, said on Monday at the Mobile World Congress in Barcelona.
