2) that lack of certainty of details means 'confusion' and reduces credibility-- rather, excessive certainty does

@phl43 @YmeKindsome @antihero_kate Finally, you note nearly all natural bat CoVs are terrible at spreading in humans.
This is largely due to poor ACE2 affinity, absence of furin site, etc.
The obvious conclusion is that optimizing hACE2 binding as the grant describes makes it more likely to have been artificial.

@phl43 @YmeKindsome @antihero_kate I conclude there is not, or at least not in this essay. You are simply missing key evidence-- the same evidence that caused me to reconsider my earlier view, which was previously more similar to yours.
