Jeff Bezos argues that humanity must leave Earth because continued energy-use growth at the current rate would consume all the energy Earth receives from the Sun in roughly 300 years.

“you know, Bezos says we have to get off Earth because at some point in the next 300 years,”

“if we keep using energy and keep growing our energy usage at the same rate that we're currently at.”

“eventually we'll be using all of the energy that the earth gets from the sun and that's true it's three or four hundred years somewhere in there um he doesn't mention that also we'd be at that point generating so much waste heat that we'd be boiling the oceans but you know whatever um and so then he says so therefore we have to go into space”
