This is completely absurd and reductive point of view, which I always assume is a cop out. Just because it's called "machine learning" doesn't mean it actually has anything to do with how human learning or human brain works, and it's certainly not "exactly how" or "very same". There's much more going on on in human creative process, aside from mere "mixing": personal experience, understanding of the creative process, technique and style development, subtext, hidden ideas and nuances, etc. Computers are very good at mixing and combining, but this is not even close to what goes into actual creative process. I hate this argument
