What happens when the current senior programmers retire in larger numbers, and there’s very few replacements because the ladder is gone?

I don’t have a solution. I’m just stocking up on physical paper books, so I’ll have something to entertain me while nothing works, until someone figures it out.

(I’m sort of joking, and sort of serious. I do expect Internet service outages to become a lot more common. But I actually just like books, anyway.)
