I think it's just value being properly reassessed to be more accurate.
Art has no intrinsic value, whatever value there might be are all external projections. If "AI" devalues art to what it should actually be, that is a good thing.
Incidentally, art has seen a slow but constant decline in perceived value over time. "AI" is merely accelerating it.
Note that this isn't to say art is unnecessary, a society without art is a damn boring one. But art is quite a ways down on the list of priorities.
As an aside, tradesmen usually make good money while artists are stereotypically broke.
But I'm not here to argue the points I've raised, only to state them, and that the debate you're trying to start is old and counterproductive and not something someone with any amount of introspective ability should want to continue further.
I've also only touched on how art has lost perceived value over time regardless, which I feel is in large part due to there being more and more an oversupply of artists as time goes on. "AI" accelerates this as I've said, but the trend itself has been around for a long time.
Art is political; it stirs passions, which is to say that it's the motive force behind (public support for) many great undertakings. In these cases, you've mistaken pricelessness for worthlessness. You're just one in a long line of very incorrect people to mis-define "intrinsic value"; designating that as a "brutal reality" is ironic, since you won't face the actual reality.
