I'm not sure if we're going for the same thing or have different views. I think especially with art there is a difference between mass produced and good things. And it's the same thing with other topics. You can buy a domestic made brand name electric drill that'll last you some time or a cheap one from china for $30. Nice clothes or the cheap ones from Primark. You can buy a deep-frozen pizza and eat that or go to the nice italian restaurant...
I don't think I have any issue with that concept. (At least in general... Sewing t-shirts in horrible conditions somewhere in Bangladesh isn't moral. But it's a stretch to apply that analogy to AI.) I mean what's the issue with that? If I want some super cheap food that is easy to prepare, I'm glad that we have frozen pizza. And if someone invents a way to mass produce frozen pizza even cheaper... I have more options available to decide which quality I like and what I can afford.
And sticking with that crude analogy... I'm not sure if we should ban frozen pizza so the italian restaurant can make more profit... In the end I think it's supply and demand and how capitalism works. I like original and creative music. There might be a demand for mass produced and cheap music, too.
Being out-competed at producing some low-quality, cheap products isn't necessarily a bad thing (in my eyes). And it doesn't really take away from the quality products. Also if someone is doing lots of tedious work and ends up with something low-quality, I'm not sure who is at fault. As far as I know there are a lot of studios and writers who pump out pop song lyrics and melodies en masse. It's not the same process as what a proper band does. And that's also something AI can't do, so I don't see any issue there.
