Misc points:

• I guessed a week to month doubling time, not six months,
• I've talked explicitly about integrated communities of faster ems,
• I used a learning-by-doing modeling approach to endogenize Moore's law,
• any model of minds useable for forecasting world trends must leave out detail,
• most people complain economists using game theory to model humans ignores too much human detail; what excess human detail do you think economists retain?
• research labs hiring workers, e.g., Intel, are willing to trade off worker speed, i.e., hours per week, for worker salary, experience, etc.; a model that says Intel cares only about worker speed misses an awful lot.
