Fortunately these government agencies are mostly corrupt, dysfunctional, and unable to recruit talent, so we probably don't have much to worry about.
While you had me nodding my head until this point, I think your conclusion is ultimately wrong. We have lots to worry about because of those very reasons you list. When you can’t recruit good talent, you get at best partial incompetence, at worst bad actors. When things are dysfunctional, you don’t have proper checks and balances. When an organization is corrupt, very bad things tend to happen as nobody cares.
If most of the talented folks are working in the private sector, it seems logical to conclude that no corrupt organization can 'hack' the privacy protections that are in place. Or at the very least, they're a lot less capable of doing so.
The pen is mightier than the sword, and corrupt political organizations will be left with nothing but a sword in the end. And that may eventually become useless, too.
You could be right, so I take it back, but I’ve heard there is some degree of strife and paranoia, but not general chaos as may be perceived.
Also, to say they are mostly corrupt or incompetent seems possibly too much of a broad stroke that is based on anecdotes. I don’t believe Snowden, for instance, ever suggested either of those are true — did he?
Finally, if this is your assessment, your standard may be unusually high. Maybe your peers, many not quite as good as you, are actually quite skilled? Just a hunch, could be wrong.
Aside from some research that the NSA has contributed to humanity, they have done little good based on the evidence I've seen.
