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 ATMs, bank drive-throughs (the ones with multiple lanes for cars) had pneumatic tubes to send cash and checks to the bank teller, or receive cash.

    Some probably still do. I feel like I used one within the past 10 years.

      They’re still in use at most banks where I live. Most hospitals use them too; way faster than dumbwaiters

      I remember those! I wouldn’t be surprised if they’re still in use. I’ve never used the drive-through lane at my bank. I can deposit checks online by taking a picture of it (which still seems weird to me), and I use the ATM for everything else.
