And most of the time savings gained from all this is blown on grind clicking "social media" so net effect is, yes, close to zero (or in more modern terms, not 100x, not 10x, but 1x at most).
Value is subjective, though. If you actually gave people an ultimatum to stop using AI tools for a year, with a negotiable price, I wonder what that would come out at. Many other personal goods are like this, they are valued highly but do not appear as commercial transactions.
