How would you feel about applying the same rule to artists?

I've seen people who work on art nonstop and think their art is really meaningful, get really into it, but there's little output that anyone cares about or that changes the world or that anyone would pay for.

On the other hand I've had friends who created some art, and have real customers paying real money, ....so it's easy to tell their art project is meaningful. (is that the conclusion?)

Maybe something (AI, code, an AI-coded project) doesn't need to have value to others or be worth money for it to be meaningful to the person who created it.
