They also need to put a little yellow star on all their clothing.

I don’t know anything about quantum computing, but recently I heard a long talk by a quantum-computing expert who were trying to convince us to work on quantum error correction. His (probably optimistic) estimate is that: with a good amount of help on error correction, we might achieve 100 logical qbit in 5 to 10 years.

Completely unpredicted breakthrough is rare in computer science; if Microsoft’s tech can actually solve quantum computing (as you discribed), it would have made much much bigger wave than this.

Okay I prefer to use FDE for security, especially on laptops, so my data recovery is never going to be trivial, yet with a live environment, also not too difficult.

Why is separating the OS with files necessary? I don’t think large files slows down the OS anymore, because of SSD.
