I agree about Engines of Cognition. It got me really interested in the parallels between information theory and thermodynamics and led me to start reading a lot more about the former, including the classic Jaynes papers. I think it gave me a deeper understanding of why e.g. the Carnot limit holds, and let me to read about the interesting discovery that the thermodynamic availability (extractable work) of a system is equal to its Kullback-Leibler divergence (a generalization of informational entropy) from its environment.
Second for me would have to be Artificial Addition, which helped me understand why attempts to “trick” a system into displaying intelligence are fundamentally misguided.
Correct me if I’m wrong, but wasn’t the problem that the government’s economic “experts” seriously believed that the worst possible thing that could happen was that the system needed a “liquidity” injection?
Well, now the major institutions are clamoring for “liquidity”, but that has by now become a euphemism for “free money in the form of a loan that no sane person expects to be paid back.”
