What is this garbage? If I own a house/gold/collectable/toilet paper during covid/… and the value goes up, am I supposed to pay taxes?
Yes, you are supposed to pay taxes on that (or on the house specifically). It’s called property taxes.
If the value goes up, you pay more taxes the next year, if the value goes down you pay less.
Well, yes and no.
Quantum computers will likely never beat classical computing on classical algorithms, for exactly the reasons you stated, classical just has too much of a head start.
But there are certain problems with quantum algorithms that are exponentially faster than the classical algorithms. Quantum computers will be better on those problems very quickly, but we are still working on building reliable QCs. Also, we currently don’t know very many quantum algorithms with that degree of speedup, so as others have said there isn’t many use cases for QCs yet.
