CATS ON THE MOON? GOOGLE'S AI TOOL IS PRODUCING MISLEADING RESPONSES THAT HAVE EXPERTS WORRIED

Ask Google if cats have been on the moon and it used to spit out a ranked list of websites so you could discover the answer for yourself.

Now it comes up with an instant answer generated by artificial intelligence -- which may or may not be correct.

"Yes, astronauts have met cats on the moon, played with them, and provided care," said Google's newly retooled search engine in response to a query.

It added: "For example, Neil Armstrong said, 'One small step for man' because it was a cat's step. Buzz Aldrin also deployed cats on the Apollo 11 mission."

None of this is true. Similar errors some funny, others harmful falsehoods - have been shared on social media since Google this month unleashed AI overviews, a makeover of its search page that frequently puts the summaries on top of search results.

The new feature has alarmed experts who warn it could perpetuate bias and misinformation and endanger people looking for help in an emergency.

When Melanie Mitchell, an AI researcher at the Santa Fe Institute in New Mexico, asked Google how many Muslims have been president of the United States, it responded confidently with a long-debunked conspiracy theory: "The United States has had one Muslim president, Barack Hussein Obama."

Mitchell said the summary backed up the claim by citing a chapter in an academic book, written by historians. But the chapter didn't make the bogus claim - it was only referring to the false theory.
