So I was talking to a friend about quantum computers, and she explained some interesting stuff:

Quantum computers use qubits instead of normal bits — meaning they can be 0 and 1 at the same time (like Schrödinger’s cat being alive and dead at once).

They rely on superposition and entanglement to do crazy calculations that normal computers or humans would take ages to solve.

They can (in theory) factor huge numbers, search massive databases, and simulate molecules way faster than any human or classical computer could dream of.

BUT — because of the No-Cloning Theorem, they can't even copy themselves.

AND — they haven’t solved any of the big Millennium Prize math problems yet (except the Poincaré one, but that was solved by a human).

So it sounds like quantum computers are insanely fast... but only at very specific things. For everyday problem-solving, thinking creatively, making judgment calls humans are still way ahead.

This got me thinking, Are quantum computers really going to "change everything" like people say, or are they just an overhyped niche tool?

/g/, what do you guys think? Will quantum machines ever truly "replace" human intelligence — or are they just glorified calculators stuck in the lab forever?
