I think the core difference of opinion here seems to stem from a different interpretation of "meaningless". You're arguing an academic definition of meaningful: can you design an AI that solves a hard problem? gambler (and I think TheOtherHobbes, who you are replying to) are arguing a practical definition of meaningful: does it solve a problem people actually have? It's neat that you can make artificial music, but actually generating music, per gambler's original comment, isn't a problem people have. It also doesn't actually add too much to culture. Essentially, the results are "meaningless" in that, even if it was successful at sounding good, what value would it actually have besides novelty?
