The argument that computer generated art is worthless because "if you want custom art, pay an artist"-- this doesn't recognize basic facts about economics. In particular, supply and demand are related, they are almost the same thing. If the cost of free art is exceedingly low, this enables me to make custom art for things that I wouldn't even consider if the price or barrier to entry or time-to-generate were higher.

> I don't want music recommendations from something that can't appreciate or understand music. Human recommendations will always be better.
While it may be true that humans understand music better than computers, the intelligence behind recommendation systems is actually not the computer programs themselves. It's the wisdom of the aggregation of many people, reflected in the numbers of the model. While talking with an expert curator about the next movie/series you should watch, or the next band you should discover would be nice, the truth is it's just not as practical or easy as firing up a computer recommendation system. While I could book an appointment with an expert music curator and go through a 2 hour interview process to find my perfect music tastes, a recommendation algorithm can still provide easy value for me.
