Yep.
But I remember reading a Stephen Jay Gould book that pointed out, eloquently, that humans, rather than being at the pinnacle of the evolutionary tree, are an aberrant side-branch, which might survive for a while, but probably won't.
Dinosaurs dominant: 150 million years.
Cockroaches doing well: 200 million years and counting.
Homo sapiens: 1-2 million years, and struggling (mostly to kill each other or dismantle their habitats).
I've never seen a cockroach smile, but I'd love to be a [whatever]-on-the-wall a few millennia hence...
C1: Remember those human thingies?
C2: Yeah. Wierd things. Prattled about a bit for a while then self-destructed, poor bast***s.
C1: Bet they'd have made good pets, though.
C2: Dunno. Bit stupid, really.
