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.
