Isn’t it amazing how this article and none of the comments on this thread address the central issue of virus mutation?
A similar coronavirus in 2002 in southern China mutated, becoming more deadly but also more difficult to transmit.
So it petered out. It could have mutated differently.
Why are people making the assumption it won’t mutate?
OK, the big possibility is that it will simply peter out and not amount to anything special. But there is that rare chance it will mutate into something bad.
So it’s wrong to think it will likely tens of millions, and wrong to think it can’t do so.
I covered mutation in my speculation as to why a lower percentage of people are dying now that early on, see above.
