> Good news, selection pressure is for more-contagious and less-deadly
The selection pressure that sometimes selects for weaker viral variants is stronger viral variants killing their hosts in droves, thus preventing the stronger variants from passing on their genetics to new hosts.
That selection pressure doesn't exist, because people are not dropping like flies due to COVID. The virus is free to mutate into something stronger because there is little pressure to stop it.
