I find this deeply troubling. So the seeds were provided by the NSA and they said "don't worry, they were generated hashing a trivial sentence. Unfortunately we forgot it now, but trust us, it's just Jerry joking about getting a raise, nothing more..."
I can't believe this didn't undergo further scrutiny earlier, and I can't believe the seeds haven't been chosen in a more sensible way, such as combining random seeds provided by different parties with competing interests, also including hardware RNGs, etc...
