These are the five technologies that the US should develop to remain a superpower, according to a report from its own Intelligence,
There was a science fiction story from the 1950s or before and it is written based in the far future and the way it is written it is clear that the two sides in the conflict are the Soviets and the US/West. The story is written in an unusual way, it is a debrief of a commander of the forces of the western side giving evidence in some sort of court or trial system. The witness talks about how their side made the best and most powerful (space) ships, but they were so sophisticated that they had old valve electronics (probably brand new stuff when the story was written). Because they had so many valves in each of their super big destroyer space ships they needed an attending ship to carry spare replacement valves and technicians to find the ones that have blown and replace them. This massively increased the cost of their space fleet at a time when the enemy was pumping out standard ships at an enormous rate. The witness then goes on to talk about a super weapon, he describes it in detail but I can't remember what it was. Anyway, they poured enormous resources into this new secret weapon but simply couldn't get it to work, while the enemy produced conventional standard weapons and was starting to take planets from them.
Turns out the witness is the commander of the forces and he wants the tech guys and the political guys who came up with the fantastic but ultimately useless super tech to be executed.
Looking at the experience in the Ukraine I would say AI will be useful, but it does not need to be sentient being level to find and kill enemy, the main failing of the western stuff is that it is so expensive, yet in practical terms most things that will kill a T-90 or upgraded T-72 will also kill any western tank so far employed in combat there, which makes all the extra costs something that prevents them from buying the number they will be needing.
They ran out of artillery shells and missiles and drones and other things rather quickly... mainly because they are so expensive.
They lack production capacity to build more of everything and when production picks up they will still be making things that are enormously expensive and getting more expensive every day.
They have air power, which has proven limited when faced with extensive and capable air defence systems. They lack extensive and capable air defence systems... which is going to leave them horrendously vulnerable to enemy missiles and bombs and drones that is going to gut their military and industrial capacity as it is, which is going to make them even more vulnerable.
The Ukraine had more weapon production capacity than the west has and probably had a larger military force than the west has since supplied and now that they are running out of men the writing is on the wall for them.
What is the west looking like in terms of MAN power?
Most of the men are getting kicked out for not being sensitive to the need of the new recruits who have fluid gender and might be male or female or neither from one day to the next.
Career soldiers getting kicked out and losing their pensions for not playing ball and simping to these freaks.
