Also many hands on productions aspects of construction (use laser cutters instead of circular saws to cut wood) are human life critical, and little money is spent on non-hands on aspects. Like the admittedly cool blueprint system being plugged. Or something like "replacing the HR and OSHA (dis)orientation class with something like coursera".

A pity the blueprint system being plugged is ipad / idevice centric. "Google Glass, show me blueprint 84Q..."
