If by that you mean "all of us" because that is the case right now. The fact that you got +5 insightful is real proof that people around here are not as good at math as they think they are.
64-bit keys are considered pretty weak, but not trivial to break, so lets assume that you have a computer so fast you can break one of those keys every second, i.e. it does 2^64 key checks per second. Don't worry about the fact that it would take a computer a million times faster than the fastest super computer in existence now to do that, we're just estimating. Now, even with that ridiculously awesome super computer, it would still take you 10 times the lifetime of the universe to break a 128-bit key. So unless there is some theoretical break on the cipher, 128 bits is secure for a very, very long time to come.
