NEW YORK: Google boss Sundar Pichai has cautioned users not to "blindly trust" everything artificial intelligence tells them, even as he struck a warning note for companies to watch out for an AI investment bubble burst that no one would be immune to.

In an interview with the BBC, the Indian-American CEO of Alphabet -- the parent company of Google -- pointed out that AI models are "prone to errors" and urged users to balance them alongside other tools.

Pichai said this highlighted the importance of having a rich information ecosystem, rather than solely relying on AI technology.
