AI can generate endless options now, but deciding what is actually good feels harder

I recently used AI while working through ideas for a poster, mostly because I wanted to see how many directions I could explore before committing to one. At first, it felt incredibly useful. Instead of struggling to come up with a few concepts, I suddenly had dozens. Then dozens became hundreds, and I noticed a different problem: generating more options was not helping me make a decision. I later turned a few of the concepts into simple motion tests with PixVerse. That made the difference even more obvious. Some images looked impressive as stills, but once they had to support movement or a longer idea, there was not much underneath them. Eventually I stopped generating and went back to basic questions. What is this actually trying to communicate? What should someone remember after seeing it? Why is one version stronger than another? The interesting part to me is that AI seems to be making production cheaper and faster, while making judgment more important. When producing another option takes almost no effort, knowing when to stop and what to keep might become a bigger part of creative work than generating the options themselves.
