How much faith do you have in your ability to generate worthwhile ideas and concepts? What is your ideal market and what do you believe people or companies will pay big money for in the future? I do think digital art is largely not worth it if you're hoping to make a living on sheer technical proficiency. If that window hasn't already closed, it will very soon.

How the art is created will be immaterial if you have faith in your mind's eye and your ability to conjure the things you envision. That's kind of what art has always been and what it will remain. You could even do this for other people. Until AI is so good that it can cut out all the back and forth and faithfully produce what the customer desires on the first try there will always be people impatient enough to commission work from other humans. And even if it gets there, still no one's going to take away your ability to create novel and thought-provoking work.

You probably need to have something valuable to say, because there won't be value in having a pretty way of saying something. I don't know about you, but I don't see much evidence of AI encroaching on the former quite yet. And when it does we're all fucked.

The market will be crowded and you'll need to stand out in some way to make a living, but there aren't many fallbacks where this won't be true, especially in the creative sphere.

And if you find this kind of stuff disturbing to a point where it fucks with your daily life, come talk about it with the other nutballs in r/MAGICD.
