Extra fingers etc are gone except if the prompt monkey missed it. Current ones you can spot by them being off / feeling off or zooming very close into the picture to spot weird transitions. It's not "20 years into the future", it's now.
I was also fooled, for the past idk 6 months social media is flooded with AI generated cat pics (and videos) and they all look pretty much like the picture. I think it was just in its training data and feels so similar because of that.
Example: Go ahead, try to spot anything besides the offness
Numbers don't mean anything, if it takes 40 hours in one game to get your character to level 20 (endgame) and in another 40 hours to level 125 (endgame) what does it matter, it's factually the same
