Depends on the (real) power you can bring up on the table; and brute force is
far from being the only possible attack; AND you can't have any idea of what
will happen is the near future (new algorythms, new CPU with calculation
power multiplied by 1e8, for example) - in this case, attacker just have to
record streams and replay them when maths/tech is ready.
It also depends on footprints you leave behind you (web, MLs, foruls, blogs,
trash can, etc), as very first step of a serious attack is intelligence.
