> It's amazing how far CRT technology got

And China is still building, today, brand new CRT boards for CRT TVs and monitors. You can buy them on AliExpress.

I don't know if CRT themselves are still being built though.

I'm hanging on to my vintage arcade cab from the 80s with its still-working huge CRT screen. Hope I fail before that thing (and I hope it doesn't fail anytime soon!).
