  • i changed my mind about gun ownership sometime in the last two years

    i used to think that like, sure i get that it would be nice if nobody in the world had a gun, but the cat was out of the bag. and remember when the covid lockdowns started? there were lines around the block at gun stores. it just seemed crazy to me to be the only person without a gun, like what if shit hits the fan?

    i think i changed my mind around uvalde, because like, that event made it pretty clear that guns dont really contribute to the rule of law. all guns did in that scenario was allow cops to kill a child an hour after he murdered 21 other children.

    i really had to kind of re-evaluate the pros and cons. sure guns would be great if, in the 0.05% likelihood event that society turns into mad max, i need to murder my neighbor for tomatoes so i can delay getting scurvy for another week. but in the meantime every single time someone has like a fucked up teenager phase or watches an insane amount of youtube incel shit or whatever, we’re making sure that they have immediate access to a means to kill like 100 people before anybody can do anything about it?

    it just doesnt make sense to me any more to live my life planning for the worst possible societal outcome in a way that has very obvious and real consequences. itd be like if nobody had invented the seatbelt and the way we prevented car crashes was having giant fucking spikes right at eye level surrounding the car to disincentivize other people from driving into you







  • ok i work in a kind of tangential industry and can kind of answer this probably

    in general the higher the voltage the smaller the current, which you’re generally happy about because your 1) electrical losses and 2) cable/wire diameter are both proportional to current

    the tradeoffs being 1) it gets harder and more important to isolate the circuit (e.g. your wire insulation that prevents the 12V bus from shorting out to the vehicle chassis now needs to be thicker) and 2) all the stuff people make for cars (i dunno, windshield wiper motors, radiator fans, whatever) is currently for 12V

    in general this move probably makes sense, provided they’re able to figure out their supply chains, and if tesla can position themselves as being like the first company to figure out a bunch of these 48V components at scale that’s probably going to be really good for them. they did a kind of similar thing with the charging infrastructure if i understand currently, like now the tesla charging cable is the de facto north american standard
