What is something that's crazier than the wildest dreams of any ~1970s nerd, but exists today? I'll start with an easy one: (europe.pub)

Blue LEDs. We had red and green since the '60s, but blue took until the '90s to figure out and the guy who did so got a Nobel prize for it because that finally meant we could use them for white lights and full-color displays.

    And yet i am this close to wanting him jailed

    Well not him, I guess, just the designers of all those devices that have a blue laser like led in it shining in my eyes at 4 AM in the morning. Fuck all those digital clocks, TVs, etc.

    No, that would be the assholes who lift their trucks, or perhaps your optometrist. Properly aimed LEDs don't blind for shit. They blind me less than oldschool projectorless halogens even.

    Nah, you're the one who has special eyes or have never driven against Teslas and such. The color temperature on modern cars LEDs already makes it feel much brighter on other's eyes, and then the actual lumens are usually more than triple the lumens compared to halogens.

    Thing is, modern headlights have very sharp cutoffs on the low beams and low beams are to be aimed down with a 1% decline. Old school ( I mean pre-projector) halogens often don't have any cutoff and just shine everywhere. A properly aimed modern light doesn't blind you significantly.

    Multibeam LEDs are even cooler, the other car can have high beams on and still not blind you.
