Note to Self: Comment on Richard Baldwin: The Globotics Upheaval: Globalization, Robotics, and the Future of Work: Start from the observation the the human brain is a massively-parallel supercomputer that fits inside a breadbox and draws 50 watts of power.
For 6,000 years, since the domestication of the horse, human backs, human thighs, and human fingers have becoming less powerful as sources of economic value, as animals and machines have increasingly competed with and substituted for them. Up until recently, however, every domesticated animal every machine had required a microprocessor. And the highly-productive decentralized societal division of labor of enormous extent created huge and increasing amounts of need for white-collar information processing: the accounting, control, transmission of information, and purveyance of misinformation jobs that are most of what people like us here do. Thus while human backs and thighs and fingers became less powerful as sources of economic value as time passed, human brains become more valuable. But now we have robots which contain their own microprocessors, and software 'bots that handle huge amounts of the white-collar information processing. So the job-creating aspects of technological creative destruction are now open to question
From this standpoint, we can worry along either of two dimensions:
