Look at music production: historically the barriers to music creation were the dexterity and practice needed to master an instrument, or multiple instruments.
But when you put tools in the hands of more people without the filter of needing the time, training and skill to coax the sounds in your head from the instrument you have… and suddenly you get stuff nobody was making before.
I mean. Do you think that there are people out there with good taste in software and imaginative ideas, who can’t pass the skill barrier currently required to write code?
Why would art be any different?
Software seems like mostly thought-stuff to me, there’s no mechanical skill-based piece. But even so, when AI can generate a full app with the ease of iteration displayed in the OP, then sure, I think you’ll see some people with app ideas generating those apps themselves, instead of having to hire contract developers. Right now just completing stubs of functions doesn’t seem useful enough to allow someone that can’t code to make an app.
Presumably we need fewer of the new more efficient jobs to displace the work done by the old jobs. But that lowers the price of ”mediocre” graphics, and therefore increases demand; maybe we actually end up with more jobs at the more accessible level.
These market dynamics are quite hard to predict but either way, bad time to be an entry level professional artist, great time to be just about anyone else.
