I really enjoyed this, and though I'm not qualified to evaluate how faithfully Janeway uses his sources or if he makes them say things they didn't, I found his argument compelling.
The book takes on what Janeway calls the "three-player game" that prevails in the innovation economy: the government, the markets, and what Jameway calls the financial industry, which to me is indistinguishable from venture capital but which in technical circles is probably only partly that.
Among the interesting ideas that Janeway promotes is that bubbles are good, for the way they incentivize and draw attention and capital to innovation, allowing for the 99 failures that surround the one success. We're so used to thinking of bubbles as unnatural and bad, it's refreshing to hear someone treat them as a natural, and desirable, part of the business cycle.
Janeway also pushes for stronger govt intervention in markets, not just as regulators, but also as financiers who serve a key purpose in being able to support projects before they are viable. I think today or yesterday, Tom Coburn is putting out another list of wasteful govt spending-- I read Janeway's conclusion last night wishing I could cc it to Coburn's office, to show him what govt can do that nearly no one else can do, and what the value of that is.
At any rate, this was really smart, and helped me to better understand some of the theory behind the market gyrations I'm interested in knowing more about. A good book, and one that I think has been overlooked.
