Again fireship make a video and show content he doesn't understand.
Wave function collapse is more close to a sudoku solver than quantum mechanics. Yes there is a "superposition of state" when computing a sudoku.
A good video about wave function collapse: https://www.youtube.com/watch?v=2SuvO4Gi7uY
Sleep sort doesn't delegate to the CPU scheduler, but OS scheduler.
It may not order items with very little wait time and often use it's own sorting algorithm.
Fireship seems to also ignore the existence of post-quantic cryptography https://en.m.wikipedia.org/wiki/Post-quantum_cryptography
Edit: I'd like to thanks OP because his list was 10x more useful than the video itself.
