This argument makes no sense to me. By this logic, the original viruses that evolved however millions of years ago were the most lethal of all time and each subsequent evolution could only be less lethal and/or more transmissible. It’s a bizarre all encompassing claim to make instead of just looking at the data that shows that delta is approximately as deadly as Covid, like that published from the UK government.
In my understanding, it is not all viruses become less deadly over time.
Rather a virus mutates in an animal, then it has a mutation that humans can catch, that first iteration will be most deadly, then become more contagious and less deadly as it spreads around.
Not all viruses are of the same lineage in that sense.

HIV did.
