Contrary to what is often believed, regarding mutations, coronaviruses behave completely differently than flu viruses. The mutation rate among coronaviruses is so slow that it's much more probable that whenever we see some new significant change among them it is due to the recombination, not due to the mutation. Coronaviruses have a specific mechanism of "error correction" in them which lowers the mutation rate, compared to most RNA viruses. The "selection pressures" are also less likely in this case then most would estimate. We as humans are much more "pressured" by this virus in its current form than the virus by anything we'd do. The viruses themselves don't even "need" to come "around" anything, and there are enough unknown viruses in the world which aren't less potential threat than this one which understandably got the spotlight. It's surely good to be aware of all the processes involved but the probabilities of different events and outcomes should also direct our responses.
