Good post, though I should point out that HIV entered the human population independently at least twice (HIV-1 and HIV-2), so your counterfactual world missing HIV might not be as likely as one might otherwise think.
(There are also counterfactual worlds where SARS-CoV-1 or MERS-CoV or similar took off as well with an even higher death count.)

Didn’t actually know that about HIV, good to know!
