One of the reasons this analogy is unconvincing is that humans have compared themselves and their inner workings to "the current technology of the time" for millenia:
- ~3rd century BCE : The invention of hydraulic engineering (eg aqueducs) in the 3rd century BCE led to the popularity of a hydraulic model of human intelligence, the idea that the flow of different fluids in the body accounted for both physical and mental functioning.
- Pre-Socratic Greece : The ancient Greeks saw the mind as a chariot pulled by horses of reason and emotion.
- 1500s-1600s: Automata powered by springs and gears had been devised, Descartes suggested that cerebral hydraulic automata produced behavior by powering "animal spirits" through the nerves.
- 1700s–1800s: The mind worked like clockwork.
- Industrial revolution (1800s) : In the industrial revolution, the mind was understood as a steam engine.
- Late 1800s : Hermann von Helmholtz compared the mind's workings to telegraphy and hydraulics; the brain was likened to a telegraph network or a complex switchboard
- 1895 : Sigmund Freud in 1895 described a Project for a Scientific Psychology using a crude neural network model and borrowed concepts from thermodynamics, speaking of psychic energy, pressure, and discharge, essentially a hydraulic model of the psyche.
- 1930s–present : "our brain is a computer"
- and 2022-now: "We are LLMs!"
I can't wait to become a quantum chip, an NFT, and so on, as new things arrive. It doesn't make any of those models accurate. They're just the metaphor of the day.
