depends. if the algorithm is safe and it's only a matter of pure
processing power, then 10k is nothing. a brute-force attack might only
take 10 million years instead of 100 billion, but that's not exactly a
difference.
the real danger is new forms of attack, and you can't possibly foresee
those, so 20 years is a very "optimistic" goal. but sheer computing
power isn't the deciding factor there.
