And quantum computers will be available in N years. The truth is that no
algorhythm can be broken by a quantum computer because they don't exist.
And when/if they do, they will hardly be available to the people that
are out there trying to crack a system. Also, following this logic, I
would suggest that you stay away from air travel, as I'm sure over the
next several decades we will be able to beam from here to there. After
all, it was in StarTrek ;-)
