Can you point to exact moment in the video, because video is long and I cannot find the argument against lab leak.
There's also an mp3 link http://traffic.libsyn.com/twiv/TWiV1019.mp3 So you can download it to your phone and listen during your commute.
Edit: Recognizing this forum frowns on snark, I will be more stoic. Whenever citing quotes in this debate, take but half a moment to observe the name of who is doing the talking; each side of the debate has an exceedingly finite set of vocal participants putting their scientific standing on the line, and, rightly or wrongly, their positions don't tend to change once made & vocalized.
So in a debate about whether person-X should have said thing-Y, it's epistemically distractibg (to oneself at least) to then go on to uncritically look at what person-X subsequently said on thing-Y as if it's unbiased, disinterested support of the position they also happened to hold earlier.
