I realize that in the present time, quaffing tankards of mead as bards
sing skalds about Einstein or Ramanujan or Telford or Bach has
somewhat fallen out of fashion.

Yup. Drinking horns all the way when I drink my mead. I have a few of
them for the traditional coolness factor. One I'll even use for coffee.
It turns out Thor likes coffee. So he's not lost in tradition after
all. Though I tend to toast Newton and Leipniz more among scientists
and more of the toasts are about military and religious leaders than
scientists. But then I'm much the traditionalist.

That's a thousand years ago. A million years ago Homo Erectus was going
from just the hand axe and sharp stick and fire to a wider assortment of
stone tools.

Humans need not *abandon* the Earth. Just exapnd to more than one
location. The redundancy of living on more than one continent has been
good in cases of very virulant epidemics - One of them might have wiped
out a population not just cut them to 10%. Thus living on more than one
planet is even more good. Or on asteriods and such including bodies in
the Oort cloud ...
