Unfortunately the tech is already here and won’t dissapear. Most people will have to become AI assisted image creators. Like you say it will make the work joyless and much more precarious. People will be required to create much more output in same amount of time. It will be more stressful and busy and the time saved will not go to them but their bosses.

AI is going to probably do that with many jobs and while everybody will point out how industrial revolution went well (we moved to knowledge work) for those who had to stay in the factories it is not so great after all. The craftsmen proud of their work became cogs in joyless process. Entirely replaceable.

If this is gonna happen with knowledge workers… great. Maybe the luddites were right.
