Viruses select only for transmissibility, nothing else. They do not select for virulence any more than any other number of factors that may or may not overall have an impact on transmissibility. To think a virus naturally becomes less virulent to become more transmissible ignores a raft of other factors such as its ability to generate viral load that the host spreads, its ability to evade host defenses, presymptomatic/asymptomatic capability of spread, etc. etc. Numerous viruses throughout history have not become less virulent even over the course of thousands of years.
