CORRECTIONS
- 10:49 Yes, I said "converges" by accident when filming and I dropped in a "diverges" in the edit. I don’t think anyone will notice.
- I think my big divergent observation may not hold! Clarence Lam was the first to spot that the lead n out the front of the series can explain the increasing times without the series itself needing to diverge. I suspect there is still an argument to be made around the rate at which times go up outpacing n, but I’m not sure it’ll be super intuitive.
-Let me know if you spot any other mistakes!
