Yeah, I'd vote for at least 12 characters until quantum computers come out... then you may need a few trillion.
I dont know whats with the fud with this quantum crap.
I see all hype around it, starting with those new age nutjobs.
I dont believe any quantum shit will come out, it's just a hype, and the quantum computer is pseudo-science.
There isnt any hard evidence that it's physically possible to build one.
Quantum computers are real and they're already in use, D-Wave has a hybrid quantum-classical system that has been sold to various titans including Google and NASA. Pure quantum computers systems are right around the corner. The implications are that encryption could become obsolete.
