Counter argument is you rarely hear of sunk-cost fallacy coming into play.

I used to do the same thing without AI, I'd spend a week working on a task and only realizing at the end it was wrong, but because I spend so much time on it, I was incentived more to keep going and ignoring sunk-cost.

Now I don't care, it only takes me a an hour and I have no problems throwing it away and trying something else.

Real life is full of unknown unknowns, AI risks putting you on the wrong path without you even realizing it.

It doesn't help a bit that (almost? I'd say all) AI products are very confident while they're guiding you on that unknown unknown path, so of course that you don't realize soon enough the epistemological situation said AI product has driven you into.
