There's certainly a contingent of younger folks that are interested in both EM gameplay and mechanics.
Restoration/refurbishment and gameplay.
It's not all doom and gloom. Very few people completely write them off anymore... Even die-hard solid state and DMD crowd folks.
As to schematics: yes, paper forever. I despise working off a tiny blurry copy or a computer screen. You have multiple advantages to working from paper. You don't have to worry about power or batteries or whatever while you're working on them, for example.
Shuffling someone's poorly printed copy of a manual can make a repair take longer than it should, despite my knowing exactly where the diagram I need is located. PG 32 is not really pg 32, if you see what I mean. *shuffle shuffle*
I will pay as long as they are being produced.
