What's a technology that was cooler in its older iterations? (pawb.social)

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.

Disney lost their old camera tech used to make a "yellow screen" with sodium vapor lights.

It's actually better than a green screen because the yellow light is so specific that even if you remove that particular frequency of light, everything else still looks fine. You can do all sorts of things that would normally be very difficult to pull off with any of our green screen tech (like drinking water in a clear bottle or wearing a rainbow dress).
