The economic systems are over-simplified, poorly automated, and disconnected from real physical and social science and measurements.

Money is a very useful technology but the 'economy' really encompasses everything, and expecting some interest rate changes to save a sick economy is like a doctor who is only aware of the existence of the cardiovascular system and has one move -- rapid chest thrusts to get more blood pumping.

By harnessing technology we can make our systems much more sophisticated than that.
