>Because AI reduces cognitive engagement with tasks

Just a sideways thing. Cognitive offloading is something humans do with each other quite a lot. People offload onto colleagues, underlings and spouses all the time.

People engage with AI through the prism of reducing engagement with the thing they dont like, and increasing engagement with the thing they do like.

It isnt a straight up productivity boost, but its more like going from being a screenwriter to a director.
