Indeed, also the whole AUKUS thing that's estimated at a third of a trillion dollars at the start, and reaching the working capacity of “blocking China’s sea with submarines” by 2040, turns out to be stillborn. By 2040, these ancient huge submarines will be easily detectable, and will be destroyed by a swarm of underwater drones.

This is a similar situation to how vulnerable tanks are to FPV drones. US clearly didn't consider the impact this sort of tech will have on the future of warfare, and doesn't have any clear response at the moment. Funny part is that US is now starting to fall behind technologically, so they don't have symmetric capability to detect Chinese or Russian subs.
