No matter how effective the NSA and the deep state and the man behind 
the curtain and J. Edgar's ghosts have been at weakening encryption 
algorithms, it's still a good idea to use end-to-end encryption on any 
emails that you want to keep private. In the first place, most of the 
people you want to prevent reading you emails don't have access to any 
decryption capability, and in the second, even law-enforcement agencies 
will be forced to get a a warrant (admittedly an easy task) or poison 
any evidence they gather. Even if you assume that the AES standard has 
custom-made holes in it for the use of government(s), the "equities" 
issue is as good a defense as any lawyer: if Uncle Sam introduces 
decrypted messages as evidence in a trial, then it has ipso facto 
admitted that it _can_ decrypt them, and thus will have compromised an 
invaluable source of information and offended some campaign contributors 
who would like that not to be true.

No matter what, end-to-end encryption buys you time: you can't prevent 
the powers-that-be from obtaining envelope data, but there are ways 
around that problem, too.
