Matt is joined by deputy editor of New York magazine and author David Wallace-Wells to talk about the new evidence for the so-called "Lab-Leak hypothesis," and about the possible origins of Covid-19. Wallace-Wells introduces the new research done by Jesse D. Bloom on possible missing tranches of genetic sequencing data from Chinese servers, and the discussion turns to what we know, don't know, can't know, and might know about the origins of Covid . . . and where that leaves us for the next pandemic.
