ONE QUIBBLE: Viruses are not ‘bad news wrapped in protein’. The vast vast vast majority of the viruses out there want nothing to do with humans at all. Even the ones that do infect humans, lots dont actually cause us any real harm, or when they do, it is by accident (HSV causing cancer). We exist today because of viruses, and they will be saving us from genetic/acquired/pathogenic diseases now and in the future. Even the ones that do harm us can be domesticated for ‘good’.
Vilification of all viruses is unwarranted.
But because this is a talk by Carl Zimmer, that is the only quibble I have 🙂
