Yes. Covid will continue to mutate to become more contagious and less deadly. This is the natural progression of endemic viruses, they don't want to kill their hosts and they want to spread.
By the time people die of covid they've already spread the virus. Generally by the time people die they've cleared the virus. It's the inflammatory response that kills them. There's really no evolutionary pressure for covid to become less virulent since people can spread it prior to being symptomatic.
"Want" in this case is clearly understood to mean the option that is evolutionarily favorable.
Per this site's guidelines: "Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith."
The one imperative they do have, in effect, is to replicate. That imperative translates into the real world into analogues of action that replicate to equivalent observable effects.
This kind of anthropomorphism is acceptable, it's not like the poster doesn't understand how evolution works... I'm pretty sure "experts" have used the phrase as well. The gist of the comment is correct though.
