He's not a clueless career bureaucrat. He's been in the cybersecurity business for a very long time (from his Wiki page):
> Alexander worked on signals intelligence at a number of secret National Security Agency bases in the United States and Germany. He earned an MS in business administration in 1978 from Boston University, an MS in systems technology (electronic warfare) and an MS in physics in 1983 from the Naval Postgraduate School, and an MS in national security strategy from the National Defense University.
While the government is often woefully behind the private sector, it's also sometimes several steps ahead.[1] You might not like his views about the right balance between security and privacy, but I wouldn't underestimate the kind of insight Alexander can bring to the table, for reasons that have nothing to do with his political pull with the NSA.
[1] Anecdote: I worked on a DARPA project about a decade ago. Commercial implementation of similar technology is probably another decade out. And that was pretty run of the mill stuff, nothing classified. I can only imagine the type of shit you run into at the NSA. The military often just hits a particular pressure point before the private sector does, and they have the money to throw experts at the problem.
