The other day I had lunch with a “brain trust,” of sorts.  Participants included a retired executive from an aerospace company.  This guy helped design and build many of the reconnaissance satellites that the U.S. has launched.  There was a senior executive from a large steel company.  There was a venture capitalist who made his first $500 million in the software industry, and who now has much of that wealth spread around in biotech and nanotech startups.  There was a former senior political appointee who worked in the Treasury Department.  And then there was me.
