Plenty of people have the resources to set up a workshop, but they don't bother. We should celebrate these weirdos (positively valenced) who make the world a little better.
If you work a good 9-5 you've got several hours each day to tinker. Also, nothing in that video was 100k+. A nice watchmaker's lathe is ~10k. A full CNC enabled Bridgeport mill is 12k. That shop could be assembled with care for ~20k, or carelessly for ~50k. It's not nothing, but it's less than a boat. It's less than a country club membership. It's less than a few trips to Disney World.
Maybe with time we'll accomplish the same thing that's happened with pre 45 steel and the instruments will need less of it. I guess in this analogy it'd be better quality filters that can detect and remove LLM-spam.
Thermal conductivity measures the heat flux given a temperature gradient. That is, how fast heat energy flows across a surface, given a certain temperature gradient across it.
It has nothing to do with the velocity of the heat carriers themselves (phonons, or charged particles).
E.g. phonons always travel at the speed of sound, in any material.
Rubber bullets are supposed to be aimed at the ground, but we've seen (pun sadly intended) plenty of officers aiming at faces/eyes of protestors. This can kill, and if it doesn't kill it maims.
They're trained to not maim or kill. More training won't fix it. More money and more resources won't fix that systemic rot.
If you've never watched Clickspring's Youtube videos you're in for a treat.
He has a long-running series where he works to make a new Antikythera mechanism using ancient (bronze age) technologies. He's a master machinist, so he has fabulous insight into workholding, precision, etc.

I'm a big fan of Clickspring. One really interesting aspect of his Antikythera mechanism videos is that, along with constructing the mechanism itself, he is using the physical details of the recovered artifact to make educated guesses about what sorts of workshop technology were available in the eastern Mediterranean world at that time. Including fairly in-the-weeds stuff like entire videos on what sorts of materials a craftsman of that era might have used to lay out marking lines on workpieces or how one might've soldered two metal pieces together.
omg, thank you SO much for the rec on clickspring's antikythera mechanism! i watched the first two episodes years ago and the algorithm never brought the channel back to my feed. now i'm subscribed and will have to watch this again.
i was also lucky enough to visit athens years ago and see the mechanism in person at the national archaeological museum... it's an amazing exhibit, and if you're ever in that neck of the woods i cannot recommend it any more. :)
My only complaint with Clickspring is that it takes so long. I feel like it has been 10 years at this point since he started the Antikythera mechanism build, but I could be wrong.
Suddenly I am struck blind and unable to distinguish any difference between Clickspring's Antikythera mechanism and Project Binky.
Spoiler warning: Starting in 2013, two mechanics graft a Celica GT-Four drivetrain into an Austin Mini. Now thirteen years later, Episode 43 came 12 days ago and they drove it. Project Binky drives!! it drives!!! In our lifetime!!
We can walk and chew gum at the same time. Charge the criminal action, fine the bad actors to help make injured parties whole, and regulate the technology to protect against future harms.
These guys will tell you their industry is more dangerous than nuclear power, and we regulate the living shit out of nuclear power. If you think models can't be regulated, look up the export controls on MCNP and tell me how that's different.
