The best writeup I've seen is actually this twitter thread from the WNYC science reporter, Nsikan Akpan (himself a phd in biology). The gist being that while lab leak is still possible, it's very unlikely and it's also likely we'll never find a smoking gun for any hypothesis. https://twitter.com/MoNscience/status/1396240581651742724
The thread's entire premise is that lab leakers are only speculating while there is in fact direct evidence of natural origins. What direct evidence of natural origins is he referring to? Kristian Andersen's argument in his oft-cited paper seems to be that the spike proteins are effective at infecting humans in a novel way, and that if he were engineering an infections coronavirus he would have designed it differentl…
This is not either/or at all!
It can be both completely natural AND also have escaped from a lab. Pretending that lab == bio-engineered is a disingenuous distraction. For the given purpose of that lab them having a lot of naturally occurring viruses is to be expected, since that is the basis of what they are supposed to research.
A lot of people have pointed that out, why do you keep touting that distraction that paints anyone serious about the lab leak question as a conspiracy nut unwilling to look at the evidence? Natural origin is accepted and does not contradict the lab escape hypothesis at all.
