What if in some years computers are that powerful they can find a bitcoin wallet with a non-zero balance with its private key?


I know right now it's really hard and it would take so much time, but what if computers start becoming really fast in the next years? like 1000 times faster? I don't know..

For example you can do it manually, with this website


A script in a really fast computer (quantum) could do it and find it?

Is there something I am not seeing?
