Some years ago I thought of an personal readio station, generated by AI. This morning another variant of that idea popped up: the eternal orchestra. An AI trained on all music of a particular composer, generating new concerts forever as if they were freshly written by Bach (or Mozart, or Chopin, or Stockhausen, or Stravinsky, or…). A dedicated concert hall could be built for each of these orchestras. And robots could be programmed to play the music on real instruments. And people could come in day and night, to listen to their favourite composer. And could come back again and again, never hearing the same composition twice. Wouldn’t that be heaven?.
