Real-life Enemy of the State, but in the worst possible way.
Red Dwarf did it better.

I'd like to see it per pound. I suspect (based on my feelings) that licensing is less per set than you might think, and that the price per pound has been trending up as piece size trends down.
I'd expect 2 small pieces to weigh more than 1 big one.
So I'd expect you to see the weight go up faster than the part count.
Not sure if that would confound or exagerate the trend.
I remember reading on HN that someone found a sim card in their vehicle and took it out.
Presumably the new ones use an e-sim instead of a physical one.

My wife bought this for our 6 year old when he was 3 and he loved it. She also bought a bunch of the other science books for babies. He insisted that I read "general relativity for babies" multiple times every night for months. He loved that I used a bendable surface to demonstrate warping space with mass. I was actually blown away that he was understanding the concepts, which I credit the books for. Adults love these books, too. Hell, for what it's worth I have a science degree and I love these books. YouTube has videos of the author reading each book if you want to preview them. I thought they were going to be a gimmick and useless, but I recommend checking them out.
I was particularly impressed by the clear explanations in 'statistical physics for babies'.
I was kind of hoping they would explain why it helps prevent chromatic aberration. Unfortunately their explanation stops short, basically just saying that 'it does' without going into the details of why.
My first guess would be something to do with it having a well suited refractive index, but it is almost equal to that of glass. The best candidate I've found is that the group velocity dispersions are opposite, which seems like it might explain it, if only I knew what it meant.
Isn't that covered in the 7th paragraph?
'the red to green wavelengths are dispersed with the same tendencies as glass, but the green to blue wavelengths are dispersed more than glass. Using a convex fluorite lens element alongside a high-dispersion glass concave lens element therefore eliminates residual chromatic aberration'
Put a turret on a vehicle.

Also the state of the art for this kind of thing is the phalanx I believe. They have it installed on carriers.

It can definitely go on vehicles.
I would say China can easily bypass this tech with hyper sonic missiles and even just launching 10 missiles at one carrier at the same time can probably fuck it up.
Just even getting one missile with a system such as this is a miracle. Anduril is far away from having the know how of building any system to the level of the phalanx.
There's a minimum size of vehicle you can mount a gun on.
The mount needs to absorb the recoil without breaking or getting pushed around too much.
The Swiss have been experimenting with recoilless chain-guns to try and reduce that footprint. Which might be interesting, but recoilless weapons are extremely unpleasant to be near due to the backblast. It still might make sense to mount such a weapon on a remote automated station, and stick it on the roof of any available truck or APC/IFV.
The hype around hypersonic missiles is overcooked. Ballistic missiles are faster. The hypersonic's advantage is supposed to be its manoeuvrability, expecting an heavy anti-ship missile to be more agile than an interceptor is just silly.
And It'd take way more than 10 missiles to overwhelm a carrier groups air defence. The combat system on an American destroyer can track "100+" targets. The carrier group has several destroyers.
In order to overwhelm the systems, you'd be getting close to the point of exhausting their interceptors. So why even bother with the fancy missiles?
Unity also got a ton of 3D models and assets, and the well-known Wētā Digital name, but yes it is strange to do this.
Looks like the digital trademark will be going back to FX, so unity isn't even keeping that.

Curious how durable a Ti shirt would be. Could it save you walking down a dark alley at night?
Looks like they're just butted rings, so you're relying on the rididity of each ring to resist opening up.
Welded or rivited rings would be much more robust. Especially vs piercing weapons, like arrows or fighting knives.
But much more expensive.
> "carbon externality charge" of $5000 on a new ICE as well, or something that scales with the carbon inefficiency of the vehicle
Your whole writeup was inspiring and gives me more hope for the future. This part, though, I'm angry about. I'm angry that we don't already have this legislation in some form. I'm sure it will be fought tooth & nail by the big auto manufacturers, but we should do it anyway. Maybe we could tack on higher penalties for anyone caught 'rolling coal', too.
New Zealand has a scheme (soon to expire with the change in government) for this.
Low efficiency vehicles are taxed on import, and the money raised is returned as rebates on high efficiency vehicles.
A Ford Ranger might attract the full fee, a new t Nissan leaf would get the full credit. A small ICE car attracts a smaller fee. Hybrids are given a smaller credit.
The exact amount of credit varied over time as the fees gathered changed.
One way to implement would be to mount a thin object , like a toothpick thickness and 1 or 2 cm long say on the mirror 90 degrees vertically to mirror surface , then (auto? ) adjust so their is no shadow from car's headlights that is behind.
Like lots of my other ideas , when i search for them , they already exist .maybe this one too
Found similar ideas already exist for car rear view mirrors .... ie Google finds ... ".... auto-dimming rearview mirror automatically adjusts to reduce glare from incident light by using sensors and an electrochromic gel layer...." However my google of words "...auto adjust reflecting mirror to face incident light...." FInd there is much discussion on Faceboot and REddit for people asking for "...mirrors that reflect very bright high been lights BACK at the driver BEHIND ...: Could not find a implementation though ... Maybe it should be an Arduino project ....
