Midjourney, DALL-E, and many of these generative AIs have reached human-level for a long time.
The problem is - unlike a human - it's pretty hard to get them to do something close to what you have in mind. Sure, if you try a few dozen prompts - you'll probably eventually get something close to what you want.
And considering the cost of this will approach free - it's going to be hard for artists to compete.
I tried getting Midjourney to generate an image of a boy doing a high jump - and no matter what I tried - the boy is hurdling over the bar rather than high jumping over it.
The quality of the images is great - human-level. But it's not what I want.
I think we'll be stuck in this phase for a very long time, like self-driving cars.
