Huh? He didn't assert that the NSA has omniscience and the ability to instantly target, decrypt and analyze every piece of digital communication in the world.

Huh? He didn't assert that the NSA has omniscience and the ability to instantly target, decrypt and analyze every piece of digital communication in the world. What he's talking about is the broad collection and storage of this data that can then be retroactively mined, possibly decrypted (for cases where encryption is even used) and analyzed when the sender and/or recipient becomes "interesting" to them. Do you think he used his work phone to call Glenn Greenwald's personal phone or something? I think it can be rationally assumed that he used the best anonymizing techniques and encryption he's aware of to transmit the information.
