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.
