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.

I like the look of vacuum-fluorescent displays (VFDs) -- a high-contrast display with a black background, solid color areas. Enough brightness to cause some haloing spilling over into the blackness if you were looking at it. Led to a particular design style adapted to the technology, was very "high-tech" in maybe the 1980s.

OLEDs have high contrast, and I suppose you could probably replicate the look, but I doubt that the style will come back.

EDIT: A few more car dashboards using similar style:

And some concept cars with similar dash:

Some other devices using VFDs:

Many receivers and amplifiers still have VFDs to this day. I still wonder why, LCD has to be significantly cheaper.

They look cool as hell though, so I appreciate that they go the extra step.
