As for Schrodinger’s cat, the fact is that any realistic cat inside a reasonable-size non-vacuum environment is never going to stay in a weird macroscopic superposition of alive and dead for more than a sub-nanosecond, if that — its density matrix will rapidly decohere to classicality. The only way to maintain a cat (with its exponentially huge Hilbert space) in an alive/dead superposition for an observable amount of time is to place the cat in a near-vacuum at near-absolute zero, but then you can be sure it’s going to be dead.
It’s sad, but the architecture of our consciousness probably will not allow us to come up with an intuitive understanding of microscopic quantum processes.
