Yeah, very smart people are exactly who we want driving innovation. Just like how Thomas Edison and his monopolizing Edison Trust brought American electrical systems into the future by embracing AC power, instead of clinging to clearly inferior DC power for as long as possible.

If you expect monopolies to drive innovation, you're going to be disappointed. A monopoly doesn't promote paradigm shifts or destructive innovation. In fact, historically speaking, monopolies often take drastic steps to ruthlessly crush any such innovation.

In your second link, at least Robin acknowledges that, historically, there is no reason to expect monopolies to behave as described. Actually, the idea of a "manic monopolist" is fairly interesting. But, if a corporation already controls an industry, how do we incentivize it to take risks by promoting rapid innovation in that industry?
