I don’t mean BETTER. That’s a different conversation. I mean cooler.

An old CRT display was literally a small scale particle accelerator, firing angry electron beams at light speed towards the viewers, bent by an electromagnet that alternates at an ultra high frequency, stopped by a rounded rectangle of glowing phosphors.

If a CRT goes bad it can actually make people sick.

That’s just. Conceptually a lot COOLER than a modern LED panel, which really is just a bajillion very tiny lightbulbs.

    Railway signalling and interlocking systems. Sure ETCS and other digital systems are far safer, but some dude at a junction used to manually reset the points and crossovers using a giant lever. Now everything’s just a digital system overseen by someone with 8+ monitors in a control room removed from the actual network.

    Also, not a technology, but rally cars used to be fully unhinged. I could watch old Group B videos for hours and never get bored.
