Once upon a time DES was good enough, now it can be cracked quite quickly, almost real-time. If computing power continues to increase at the same rate, today's stuff will one day suffer the same fate. We're already recommended to use larger key sizes because 1024 bits can be brute forced. the information being protected may not be relevant by the time it's easy to crack - a bit like the old Playfair cipher used a hundred years ago - it could be cracked in a few hours, but if the message was "attack in 15 minutes" then it would be somewhat out of date by the time it was cracked.
