“So many AI researchers have started smoking as a way of signaling to other researchers how much they believe in AI,” Sankar said in an interview on CBS News’ “Face the Nation” on Sunday.

The logic, he said, is: “I believe so much in AI that it’s going to cure cancer. So I’m showing you my chips are all in.”

Sankar did not name any researchers or provide evidence for the claim. Smoking remains a major cause of preventable illness and death, and no AI breakthrough has eliminated the health risks associated with cigarettes.
