I don’t think anybody’s tracking the actual net-effects of any of this crap on productivity, just the “vibes” they get in the moment, using it. “I got my part of this particular thing done so fast!”
I believe that to be the case, in part, because not a lot of organizations are usefully tracking overall productivity to begin with. Too hard, too expensive. They might “track” it, but so poorly it’s basically meaningless. I don’t think they’ve turned that around on a dime just to see if the c-suite’s latest fad is good or bad (they never want a real answer to that kind of question anyway)
