Any objective source for your claims? If your basis is the attitude for such agencies here on hacker news, it’s understandable why you might believe those to be true, but they aren’t.
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.
