... was against writing. Because it would degrade the memory and reasoning skills of scholars who became dependent on it.

It's not the tools on the institutional end of the educational transaction that matter. Its what the students utilize to accomplish their end.

Reverting may introduce another critical fix that the current software dealt with.

Fix-forward is probably the only way to maintain safety certification for known issues. And it's not like they are ripping out half the plane here - these systems are meant to be swappable during ground service. The terminology being "Line Replaceable Unit" or LRU.

Consumer passenger planes do not need to be rated against nuclear EMP. ECC memory is enough, and if you don't have ECC then you need to implement checks for cosmic-ray induced bit flips with other checksumming methods. Also, avionics systems usually act as a quorum between cluster members, so if one member has a bit flip and the other two don't agree, the bit-flip is reset.

The real issue is that if you have to sneaker net updates onto planes, airlines just wont update.

This extra proves you have no idea what you are talking about. How do you think airlines load a few terabytes of entertainment videos on each aircraft? Via data loader, while the plane is on the ground having baggage removed and loaded, passengers deplaned and embarked, and the aircraft is being refueled.

Manual updates of software loads happen all the god damn time in the 40 minutes a narrow-body airliner is on the ground, from the ground ops personnel.

Congratulations on knowing absolutely nothing about the avionics industry.

Here's a hint: aircraft are purposefully not doing over-the-air updates to safety-critical systems because rapid software delivery is not needed nor wanted for safety-critical systems. To do so would INCREASE the frequency at which we see things like this, and reduce revenue service time of the aircraft if not worse.

It is impossible to launch Soyuz/Proton rockets without this service cabin. The launchpad itself is a huge slob of armored concrete with a hole in the center, used to direct hot gases into a gigantic pit, ot takes a few years to dig out that pit and build the multistory tall launchpad. The service cabin is a multistory metal structire that provides access to set up various umbilicals and to set up the chemical matches, lit electrically, that are inserted into the rocket engines (yes, that is how they light up these types of engines, huge, many feet long, matches). The cabin then slides away into the wall and it is supposed to be fixed in place with some pins. They did not do it this time, so the engine exhaust pulled the cabin out of its niche and blew it out through the vent hole into the pit.

Ukraine did not fold to the threat of the USA stopping all support earlier this year, it will not stop to any of these threats now either, it is a non starter. Zelensky doesn't have the mandate from Ukrainians to this type of a "peace deal" just because USA may stop any support. Ukraine will endure wothout the USA support, just with more casualties.
