Yeah, I'm realizing I have two contradicting notions in my head about that now. Is there still some sort of mapping being done, by any other name than CMB though? That thing we were all excited for a peak of about how the universe X billion years ago was shaped?

Re: your edit - I'm open to being rebutted here but, I think that clip might be a bit outdated. H1N1 is Swine Flu and Spanish Flu. If we're doing podcast links, RadioLab covered this topic again during early Covid. Current scientific papers and articles on the topic all seem to understand and accept that H1N1 is the virus in question in both cases.

Just to follow up on the re-emergence question. Here's a fun fact about the original Influenza epidemic we call the Spanish Flu; H1N1: It actually died out, once.

Partially from its own mortality rate, partially from built up immunities over time and evolving variants, but by the time we understood what viruses really were and how to approach them, there was no known surviving sample of it.

Before it died out, though, it passed on, first into the birds as H1N2, swapping out one bit for another, and again into pigs as H3N1, which themselves eventually crossed and produced H3N2, but enough mutations and variations kept the base nodes on infrequent rotation over the years. And eventually they met and hot swapped again, giving us the "Novel" influenza virus we called Swine Flu, H1N1.

And at some point, someone found an inexplicably well preserved vial of blood containing the Spanish Flu from back in the early 1900s, and tested it, confirming suspicions that yes indeed, through a series of exchanged hands, swine flu was a perfect re-assembly of the original Spanish Flu strain of influenza.

Tl;Dr - re-emergence is entirely possible even when the given strain has already gone extinct. Blind mutation and hot swapped component parts can always put Humpty Dumpty back together again.

They were referring to the current cord-cutting generation, I assume. Analogue broadcast TV went offline in America years ago so you'd only get TV if you paid for cable or some equivalent service. Plenty of people opted to just stick to streaming services and "cut the cord".
