So I don’t think art is “harder”. It’s just harder for the average practitioner/professional to find “success” (however you like to define it).
Of course software gets copied all the time, but we have jobs because so much bespoke software is needed. Looking at some of what AI can do now, I wouldn't need surprised if our floor gets raised a lot in the next few years as well.
Are artists really "doomed"? Or are they just worse at redistribution?
Be entertaining. Be outrageous. Be endearing. An AI can't cut off their ear.
We're all "doomed" if this is the case.
