Since you quoted that super villain Friedman, it's a futile exercise to discuss this issue with you but touching on the silly analogy cited by Dr. Evil: Abandoning spoons to shovels ==> 1000X efficiency gain and net positive mass-scale job opportunities Abandoning shovels to heavy equipment ===> 100X efficiency gain and net positive of mass-scale specialized job opportunities. Abandoning manual trucks to fully auto ===> ~1X efficiency (disputed) and net negative of job opportunities for the masses save for highly specialized super white collar jobs such as for engineers and developers like us. Do you really think that it's OK from an economic point of view and not politically as this is almost settled to destroy the livelihoods of these poor & lower middle class people just to get an estimated albeit unrealistic 100% efficiency boost? Are you ready to pay the price in terms of increasing crime rates and lower median quality of life and seeing decrepit hoods everywhere except inside your gated community where you plan to hide from all those poor people and truckers-turned-criminals on the street?
