Every company would be affected if the AI bubble were to burst, the head of Google's parent firm Alphabet has told the BBC.

Axar.az reports that speaking exclusively to BBC News, Sundar Pichai said while the growth of artificial intelligence (AI) investment had been an "extraordinary moment", there was some "irrationality" in the current AI boom.

It comes amid fears in Silicon Valley and beyond of a bubble, as the value of AI tech companies has soared in recent months, and companies spend big on the burgeoning industry.

Asked whether Google would be immune to the impact of the AI bubble bursting, Mr Pichai said the tech giant could weather that potential storm, but also issued a warning.

"I think no company is going to be immune, including us," he said.

In a wide-ranging exclusive interview at Google's California headquarters, he also addressed energy needs, slowing down climate targets, UK investment, the accuracy of his AI models, and the effect of the AI revolution on jobs.

The interview comes as scrutiny on the state of the AI market has never been more intense.

Alphabet shares have doubled in value in seven months to $3.5tn (£2.7tn) as markets have grown more confident in the search giant's ability to fend off the threat from ChatGPT owner OpenAI.
