IMHO they didn't list key reasons for the startup and productivity slump. Most managers with their hands on investment money don't invest in long term productivity improvement technologies as external ventures. Internally corporations squeeze out basic research needed to feed an early pipeline for productivity improvement. And a corollary, the people with visibility into hands-on productivity improvement area, broadly don't get paid enough to invest into a small venture themselves. (software is something of an exception here both for better pay and lower entrance costs.)
