Most virologists are either silent, say it’s too weird to guess where it came from, or state the obvious that it’s unnatural and lab-made. 50 mutations would never occur in such a patient. I think I read the most they’ve seen are 12, and it would not have immune escape properties or be contagious.
The US doing a 180 on policy proves they know what it is. I’m sure it surprised them, they had nothing to do with it. But they know where it came from. I don’t think this was an accidental leak it’s probably a Ralph Baric special or somebody else with similar knowledge and experience created it. It also acts more like an RSV than a coronavirus and the S1/S2 site is different in a good way. It has ALWAYS been possible to make and distribute a less virulent strain that could outcompete other strains, however, conventional wisdom says that’s crazy and could kill hundreds of thousands of old people. Some man man or men (or women) decided to take that risk. I doubt they’ll confess any time soon, but I think the crazy theory that it was lab made to end this thing isn’t crazy at all given the outcome
