I don't see that as Darwinian. Darwin just describes what happens and how that led to differences in species, he doesn't give it value judgments like "net positive" afaik.

And neither do I give a value judgment on the difference in alert level between the yearly Influenza and this Corona outbreak: I’m just - speculatively - attempting an explanation, without necessarily endorsing it.

It’s the same reasoning behind the alarm behind HIV in Africa: not only it kills, it removes the economically active demographic from the economy while tying up even more in their assistance...

Everyone please take time to read and make sure you properly understand what you have just read before reacting.
