Personally I find quantum computers really impressive, and they havent been given its righteous hype.
I know they won’t be something everyone has in their house but it will greatly improve some services.
I think the big breakthrough was in cryptography, and yeah, most people don’t care. All of your passwords will be useless against brute force attacks in 10-15 years from it tho!
Even “quantum proof” passwords are trivially broken if quantum computers allow us to practically solve p=np.
That’s a pretty big assumption though, and even then you can just switch to a new password format that allows for passwords that aren’t solvable using mathematical means. e.g. my password is to fill in a picture on 10x10 grid using 10 different colours. There’s no mathematical basis to guess my picture and there are more posibilites than there are particles in the observable universe.
