Your opinion of an average person is overly negative.
Generated shit is the new Muzak, the new Alegria clipart, but done very badly. When a person who doesn't care about music and doesn't understand music hears Muzak they don't think about it at all, that's kind of almost the point of it. It's an amalgamation of a corporate default sequence of sounds invented to be approved by a committee. And that's the best that generators can wish to do, and I suspect there is a fundamental quality to it that will prevent it from being that ever.
That's the thing about art, intentionality, it's not that "human art" is somehow superiour, it's that only human art exists, copying algorithms are doing copies, and even if sometimes it works, you don't get art without an artist saying you something.
Obviously, people who don't enjoy art don't care. But that doesn't really matter.
