I think it's a sort of slot machine effect, you get used to losing and when something goes slightly well you wildly overestimate how good it is. You see this with visual artists who got way too into image generation. Because they have to spin the wheel a thousand times to get one good output, they have totally habituated themselves to a lower standard by the time they emerge from the AI mines clutching their one good output, because that output is not all that great.
It looks good compared to all the failed generations though!
Also, spending all your time cranking the slot machine handle and occasionally winning convinces your brain that you have a magic ability at cranking the slot machine handle, when actually you were at best slightly lucky. So you get people who convince themselves they are geniuses at using AI when they are actually average or slightly above average.
