Even grover's algorithm would only cut it down to 128bits which is still "boiling the oceans" territory. So at least in that area we have a lot more safety margin than in the past. Of course none of that is a guarantee that the data will stay secure, but you can't just generalize all attacks used in the past and then count them against a system where we learned from some mistakes and others simply aren't applicable.
