I understand the sentiment, and I’m definitely not a Boeing apologist. But the first version of the Apollo command module killed three astronauts. They had growing pains, too.

I had to stare out a window for a little bit after this one.
Beats me. I’m just a chemist who managed my facility’s NMR magnets (built like MRIs but with different electronics for chemical analysis) for a few years. We had to pull some stunts to keep those magnets alive sometimes, but it was always a matter of how soon, not if, a shipment of cryogens would arrive. Can’t imagine trying to keep MRIs from quenching in a war zone.
No idea, but if it were up to me I’d spend that rationed power on ventilators and such keeping patients alive. Losing cryogens stinks, but you can top them off without any power as long as you have stock or deliveries. And I’d rather a magnet quench than have to explain to a dead person’s family that their loved one’s life was less valuable than some helium and a chunk of ceramic.
The cryogens boil off at a pretty consistent rate no matter what, but the recovery/recompression systems do require power. So once power is cut, any boil off isn’t recovered.
Superconducting magnets (like in MRIs) can run effectively forever when at the right temperature. Turning them off requires a complex process of draining off that current slowly and carefully so that the magnet isn’t damaged. Hard to do on a normal day, and profoundly harder if there’s no power.
Any free weather data is either being subsided by the cost of the device or harvesting your location data for ad surveillance purposes. Paying for carrot means the developer gets to put food on the table without telling ad networks wherever you are.
Yeah, that sounds like seizing Russian assets and selling them to the west with more steps.
