In the course they were describing the SaaS infrastructure like Amazon and how you can rent huge computing powers for little money. You can actually rent a lot of power for $ 200/hour which is equal to the bill you get from a lawyer or consultant.

I remember in my first startup when I needed a NDA document, I went to a lawyer to help me out. Well, in the future I would go to an online Intelligence Service and build up the NDA together with this all knowing AI system, using nothing but my tablet and a credit card. Looing at Watson, the big computer system from IBM that won Jeopardy, the technology is there.
