As an artist I am concerned about AI image generation

There is a response to this tweet where someone says "stop gatekeeping art" which while I understand the gist of what they mean, seems like a weird thing to say to console someone who is concerned they are about to be automated out of a job.

I guess the context is "as an art seller, I am concerned", not so much "as an artist". Which is understandable, of course, as much as anyone would be concerned if their job is in jeopardy.

But framing it as a matter of art does sound like gatekeeping. It'd be "that cannot be art, because x" when all they mean to say is "please don't stop paying me for this".

I don't believe they are framing it as if it is not art. The problem they are raising and that it is an AI trained on other peoples' art down to copying their signature making it appear as if it were a genuine piece from that artist and of course yes, they are concerned that they are watching their career die in real time because of it.
