Kevin Drum had a good summary of this a couple of weeks ago, much shorter. His take? There's no more evidence for the lab leak theory now than there was a year ago,
BUT what has changed is that the cross-over theory implied that we would find certain evidence for the vectors, and that evidence has not shown up. KD's take was that it's not so much that the lab leak theory has become more likely, it's the that biological origin theory has become less likely.
