I think it's also that drones can't hold ground. If drones could do all the jobs of infantry and armor, they wouldn't be offense-dominant or defense-dominant, but ground drones are not mature enough to dig a trench or engage in a firefight.
Space power means NATO drones larger than a few kilograms will probably be unjammable, because they connect to Starlink. China just had a study and the upshot is you need air superiority and hundreds of large EW drones to jam Starlink, which is difficult to achieve when your own drones are vulnerable to EW. I'm not sure if NATO would actually have enough of an mass advantage in space to shoot down Chinese satellites, but it seems like satellites can be small enough that hiding "major force movements" would be difficult for any party
Makes total sense, AI images are higher resolution than classical pictures (which are limited by the dexterity of the painter), so you're basically getting 11.67 pictures in each.
Just so happens this friend had an oxygen concentrator in storage. He'd acquired it during Covid back when they feared hospitals might be overloaded or highly risky.
This brings back memories. At the start of Covid I bought two used oxygen concentrators, a few "toy" concentrators off Amazon, and lots of tubing, hoping to build my own high-flow nasal cannula setup. I even went on Alibaba and bought a pallet of CPAP machines, but they couldn't deliver on time and the supplier said they were needed in developing countries so I canceled the order. I highly recommend this kind of thing as an exercise in agency, particularly the part where I had to understand the reasoning behind various medical standards and get out from behind chesterton's fence.
Anyway, glad your child is ok!
Blue Origin just landed their New Glenn rocket on a barge! This was an orbital mission to Mars, which makes them the second company to land an orbital booster. For context, New Glenn has over twice the payload (45 tons) of Falcon 9 (~18 tons reuseable), and half the next version of Starship (100 tons). Not many were expecting this.
SpaceX did this in December 2015, nearly 10 years ago. But going forwards, their lead will likely be smaller. The next milestone is to land a booster five times (June 2020), and between Blue, Rocket Lab's Neutron, and numerous Chinese companies I would be surprised if it takes until 2030.
My guess based on reading anecdotes like these and Berger's books is that the algorithm is a vast improvement over anyone else's engineering practices, but it alone doesn't tell you what else you need to run a company. Maybe systems engineering is the missing piece, maybe some other management philosophy.
If you look at the major SpaceX programs, they are: Falcon development, operations, Starlink, and Starship. The first three were wildly successful, and Starship is late but technically and operationally superior to other companies (e.g. Raptor engines are double the chamber pressure of BE-4 and there have been 10x the test flights), with successes directly traceable to each step of the algorithm, and wasted energy due to not doing something else when appropriate. Raptor 3 engines are only possible to make as cheaply as Elon wants because they had a vast number of parts deleted; yet they also "accelerate"d to build hundreds of Raptor 2s which are now obsolete.
1Hard to answer this question because there's a tradeoff between noise, airflow, and surface area with air purifiers. Eg if you cover your ceiling with air filters, the noise will be minimal.
I'd say if you have enough output power and are only limited by uv exposure, it's vastly more effective. I had to buy a couple of expensive Clean Air Kits purifiers to get ~25 air changes per hour in a smallish room, but 100+ equivalent ACH is possible with far-UVC, either by using light filtered to 222nm or keeping it in some kind of ceiling louver that traps the light. Not sure how the cost compares though, as they seem to be limited by output power / $ rather than safety limits.
This paper happened to be the only one with a perfect score at NeurIPS 2025. Congrats to the authors!
Drone carriers seem extremely important. Probably half the missiles and all the attack helicopters on every ship should be replaced with drones that cost 1/20th as much. The America class, which carries 20 helicopters and some F35s, seems completely obsolete given it has no drone infrastructure. The Chinese Type 076 at least has a small catapult for drone launch, but both should really carry at least 50 large jet powered drones, 500 loitering munitions, 500 recon drones, 20,000 FPVs as well as surface and undersea drones.
