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.

At my job we recently had an old device that was used to produce the sound a phone makes when the line is busy, open, etc. . It's about arm length and 20 cm thick, you can distinguish the cogs producing the phase from the signal.

My grandmother was a switchboard operator at one point in her life. She saw a scene in Mad Men and said they left didnt get the sound right but it might as well have been where she worked
