Interesting concepts there, as applied to psychology. And kudos for making it available freely. Definitely worth a read imho!

Skimming through its chapter on AI, made me think of Dave from EEVblog fame. In some of his videos he wears a T-shirt saying "always give negative feedback!". Which is correct - for those who understand electronics (specifically: opamps).

In short: design circuit such that when output is above target, circuit works to lower it (voltage, in this context). When below, circuit works to raise it. Output stability requires a feedback loop constructed to that effect.

There's analogies in many fields of technology (logistics, data buffering, manufacturing, etc etc, and yes, thermostats).

I'll leave it there, other sites like Wikipedia (or EEVblog!) better explain opamp-related design principles.

From what I've read, current AI systems appear like opamp circuitry with no (or poor) feedback loop: a minor swing in input causes output to go crazy. Or even positive feedback: same thing, but self-reinforcing. Guardrails are not the fix: they just clip the output to ehm.. 'politically correct' or whatever. Proper fix = better designed feedback loops. So yes, authors of this book may definitely be onto something.

An emotional analogy I've often made, related to EE, is automatic gain control. When you experience long periods of emotional stability without significant highs or lows, your brain applies a form of gain control. This makes the threshold for something amazing very low and something awful very high. As a result, people can feel overwhelmed by relatively trivial issues. Many self-help books, religions, and philosophies emphasize appreciating past experiences or considering how situations could have been worse. I see this as a way to counteract the brain's natural tendency to adjust its gain control.

Been a long time since my ee courses (a degree I never used...but I digress...). How did that saying go?

Want an oscillator? Design an amplifier. Want an amplifier? Design an oscillator.
