Can't tell you what exactly Vision Pro is good for – just my gut feeling that it'd be good to play with. Maybe make an early app; who knows.

I think the hippies were rather misunderstood – people wanted to see a great socio-political movement in it, but on the ground, it was a self-destructive mess. Didion wrote good accounts of it in Slouching Towards Bethlehem. The mess was slowly moving towards its religious roots, backward from what many claimed it to be. But that's my humble interpretation.
Soviet hippies were, of course, totally different animals.
