i'm just trying to be nice here. some things actually boil down to economics and human needs (hash functions are produced by devices that have to be demanded for this use). some things boil down to the algorithm or state machine or distributed system. everything does fundamentally start with two ingredients: energy and materials, and below that level, you start to have matters relating to known and as yet unknown ways to reduce either energy or material costs, and thus lower (and by Jevon's paradox, increase demand).
i would love to hear what you write after you read Human Action. the quantum state and time questions are interesting when you are examining the fundamentals of how to produce things, but understanding the why, the human motivation, is far more generally applicable and interesting for solving problems.
i get it, that the quantum fud is extremely specious. but that isn't solving any problems, and solving problems is the whole purpose of asking the question in the first place.
in my opinion, it is more likely someone will break a pubkey with a supercomputer than a quantum computer.
you are letting the fudsters get under your skin
