Hahaha, some of the experiments around AI by the big companies is very interesting. The Facebook one indeed. The Microsoft one as well with the Twitter bot that went totally racist and mean. A few times I talked about AI generated music with some of my friends being professional producers and DJ's. Though they are technical, they generally believe AI will not replace them... But to be honest, I think AI can replace the producers and musicians. That said, when so, it'll be the live performances that'll be the unique element of a human artist. Sure, also their own 'manually' created music, for their best fans, but the mass will not care too much anymore in such future. I suppose the circle will be back to where music was before all the technology, like recording possibilities, back to performing, rather than creating and mass distribution.
