Not too sure about that, that might be the case but currently, they would need much more training to not mess up facial features, to make images truly lifelike and to follow prompt instructions better.

I’ve used dalle a fair bit and I came to the conclusion that you will never get a truly accurate representation of a person, such as hair on a bald persons head, stubble turning into a moustache, tons of wrinkles for no reason, etc. It only seems good at generating cartoon characters, even then though, there are still inaccuracies.
