Haha! That's what I'm finding myself doing at the moment, wasting so much time just rolling and re-rolling images, re-typing prompts, etc, that next thing I know half the day has passed and I haven't eaten yet or done anything important.
Instead of writing chapters for my novel, I'm generating pictures I won't even use for it! XD But I'm enjoying it!
It is a lot of fun, I'll definitely agree there! I think if a person had a lot of time to really understand how to best prompt for what they're looking for... and what model to use... it could be really useful. Definitely not as easy as just paying an artist though, but for folks like me who find it hard to come up with reference material to give to artists, it's a big help to be able to say "I want this pose and this vague style from this midjourney output, but not jank".
