As a person whose is in a position similar to his, I agree with the spirit of his comments. Basically, what are things of value in this world? Scarcity is probably the biggest driving force, especially when coupled with demand. It's what drives the prices of precious metals and stones, truffles, caviar, etc. The same logic applies to any business. A high barrier to entry is one way that a business keeps competition at bay. Specialization of skills is another. Of course, having a specialized skill loses its value when there is no demand for that skill. As a programmer, part of my job is learning new things before everyone else so I can stay ahead of the curve. Once the world catches up and the technology becomes commodity, the money dries up. For almost all things related to technology, from hardware to software, it's a race to the bottom so you had better jump to the next train which is still moving.
