Literally no one, no one even claimed we would work less due to AI. It is one of many absurd claims about AI here. There was no period in which we would get think pieces predicting more leisure time.

We had plenty of think pieces about making people obsolete, about destruction, generally in celebratory tone. I cant even think of period where AI think pieces would promises much positive - it was sold to CEOs, so pitch was always "higher unemployment".
