Basic FPV drones are rapidly getting countered/obsolete. The moment people start doing something smarter/custom the drones stop being cheap. It's an unavoidable dilemma: commodity stuff is cheap, but easily countered; stuff t

They are only a thing for navies that can't afford anything better. We just call our battleships "destroyers" now, Burke Flight III and Type 45 are almost exactly the size of HMS Dreadnought and half the displacement (we don&

Both sides suffer from shell and ATGM shortage and inability to suppress/destroy air defences, which drives suboptimal adaptations. An FPV drone assembled in a garage from aliexpress components and a tesla battery [1] with a submunitio

We had pretty smart weapon systems for a while now! P-700 Granit and Brimstone missiles were doing cooperative engagement and target selection for decades. BONUS rounds fit target recognition into small pucks. If we squint just a bit, many

I don't think we as laypeople should even attempt to draw conclusions from Ukrainian battlefields ourselves, seeing how strong the survivorship bias is. Take FPV drones. In [1] Michael Kofman estimates (based on talking to a number of

Only if plastic packaging ends up in a landfill, if we burn it we still release the carbon into the atmosphere. "Bioplastics" (ie made from atmospheric carbon captured by plants) are a better example, and if we landfill those they

I love Barbican. One often overlooked quality of Barbican is how much design work went into it: these corridors, galleries, balconies are all unique, many design elements are one-off, and there are more than 80 flat types https:/&#x2F

Your DJI can't cope with doors. 100g of explosives don't do much, see Ukraine where this was attempted multiple times with very limited effect. And most importantly, your DJI enjoys massive subsidy because it is mass produced for

The context of my reply is that "slaughterbot" short video, not 100kg+ drones. It goes both ways. Just half a century years ago plenty of people were convinced we'd be having flying cars by now, projecting the speed of progre

They aren't free. Autonomy is computationally and sensor hungry, and consumes a lot of power. The moment a platform approaches the capabilities you are thinking of, it stops being cheap and stops being small. All while those drones are

Out of interest, since you seem really knowledgeable: is there any reason no one ever mentions shipping VT fuzes to Ukraine? They seemed to work really nicely in the Battle of the Bulge, and the US is likely to have a vast stockpile of Cold

Problem is, "rational" is not objective. "Rational" is more like "consistent with one's goals (subjective) under one's perception of reality (subjective)". When you're saying "Putin invaded

There's nothing to "pwn", you can maybe turn some switch ports off or change your SSID. It doesn't do routing or firewalling, that's on you.

This is incorrect, and I think this kind of low effort copy-paste of whatever ChatGPT came up with is actively harmful to the discussion. Honestly, I think this practice should be explicitly banned here. > Distance: The average distance

"Estuary English" is the closest to the "default" there is today. RP is coded posh, Estuary is "vaguely from around London" without any particular colouring.
