Hell, all the best instruments will eventually end up in the hands of billionaire collectors who will consider them too valuable to be played. They'll end up hermetically sealed in lucite and sequestered away in exclusive collections... an artificially tweaked economy surrounding them to maintain and increase their value as investments. There'll be no decent wood left on the planet to make more and music will be created by computers anyway. Laws will be passed to punish those found hiding in secret enclaves playing real instruments. Legends and fables will grow up around giants of the past who could tease enchanting sounds out creations made of wood, leather and primitive metals, the technology to create and play these things lost in the misty, smoggy, golden past. Soon people will doubt the veracity of those stories and imagine the few preserved instruments to be fetish objects never really meant to be functional. And then the sun will wink out of existence. Sweet dreams, kiddies.
