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.

Surprisingly, 3D printing is where most of the firearm innovation is happening now. Some use off the shelf parts from common guns like the AR-15, others are completely printed. It's a weird rabbit hole to fall into, but definitely interesting.

The "should this be legal/illegal" debate is its own rabbit hole as well.

It always struck me as weird that serial numbers and therefore the weapons tie to the owner are printed on the receiver. A receiver can be milled with a simple CNC mill or as recent development shown using 3D printers. We should rather serialize and register barrels, the one thing that needs highly specialized equipment to manufacture and what defines the guns caliber, potential muzzle velocity and has unique thread profile.
