What's a technology that was cooler in its older iterations?
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.
Before transistors there were vacuum tubes which did the same thing but using very different principles (and were also way bigger, even than traditional transistors and billions of times more than the transistors in the most modern ICs)
Before electric milling or even steam milling, flour used to be milled using watermills and windmills which, IMHO, are way cooler.
a 127mm vacuum tube, quite large, is equivalent to 127,000,000 nm which is only 63.5 million times bigger than a cutting edge transistor so that estimate seems a little exaggerated.
I love seeing old workshops where all of the machines are powered off of a single source of rotational energy. Just so whimsical and kinetic when everything is moving
