Why humans will perish rather than become grabby aliens

It turns out that Homo Sapiens is not all that different from other, early proto-human species, such as Neanderthals.  They are the “closest things to us.”  Denisovans, etc.  We killed them off.  (We also are likely to mostly kill off chimpanzees, zoos and research labs excluded.)  Therefore the best prediction is that we kill us off too.  The other species like us died through mass violence at the hands of humans.  We don’t have many data points, but they all seem to end the same way.

You might think a) “we are really good at killing off other species,” rather than b) “we are really good at killing things off.”  Therein lies some hope.  Signs of cross-national solidarity thus should make you much more optimistic about the future.

How’s that African vaccine distribution program coming?
