Indian-origin CEO of startup Delve Karun Kaushik shared a picture of his AI engineer on his "third all-nighter". "This team never stops shipping. We're revoking his git if he doesn't [sleep over 10 hours] today," he said. US millionaire Bryan Johnson criticised the post, saying that "three all-nighters = impaired glucose metabolism...and cardiovascular strain" and called it "shipping death".
