Scariest part about this interview is where they talk about the future where employees will all be assigned a ranking according to their insider threat.
I am taking the same steps. I am currently working, but am also looking to stand up a security consulting firm/start-up on the side (I have my employer's permission). Multiple income streams seems to be the only way to mitigate the risk of losing a job in the future. That and building wealth (if Tom Piketty is right).
The "new economy" is a much less friendly one, and I am also personally terrified of my coming professional irrelevance. Savings are nice, as is the social safety net, but I've seen them both either fail or get used up. It is a perverse culture where you fear the fate of your father.
