A decade into the future, after a widespread apocalypse, these two groups of remotely living and drug enlightened peoples will wage war against each other for the rights to repopulate the earth.
Burning Man will win and the world will be cast into shadow (with lots of tracers and glowsticks) for several centuries, after which, visiting aliens will have colonized Earth and turned mankind into a slave-race. Finding them less than optimal the aliens will infuse new genetic material into our DNA, unknown to them, that this is the sixth or seventh time this has occurred here. The genetic material that they fuse to our helix-like strains of DNA will trigger a mutation, giving man god like powers and hastily beating back the alien hordes.
Maybe I took that a little to far... but that's my prediction.
