I know evolution is ASB, but HIV evolved recently, in the 1920s, in specific circumstances, namely Leopoldville's brothels with rapid turnover of sex workers; without such turnover, SIV would not spread enough to evolve into the nastier HIV.
If that did not happen, what would the effects be? Butterflies would of course eliminate anyone born after, say, 1920 in OTL, but they would not change major social and political trends until at earliest the 1980s. WW2, the Cold War, decolonization, and the social protests of the 1960s would happen on schedule. But what then?
