Michael Nielsen's mental models

4 claims Michael Nielsen made fit 3 mental models. Most often: S-curves and diminishing returns, Bottlenecks, Specialise and trade. Everything they said here.

Models they name

Their own words name the idea.

S-curves and diminishing returns

Most growth slows as it matures; the question is whether the curve is flattening or something new is restocking it.

Diminishing returns in science is a snapshot illusion: somebody keeps restocking the table, and new fields make progress easy again.

  1. Michael Nielsen Physicist, writer and researcher if somebody, you know, is standing behind the dessert table and is replenishing, restocking the desserts and keeps kind of you know, adding adding new ones in, it may turn out that you know, a little bit later a much better desserts appear.

Diminishing returns in research are not intrinsic to the world: they are what you get when the institutions around research stop changing.

  1. Michael Nielsen Physicist, writer and researcher If you're not changing it, if there's some kind of stagnation there, if you're not changing those external sort of circumstances, yes, like you may start to get sort of diminishing returns again. But that doesn't mean there's anything intrinsic about the situation.

Bottlenecks

A system moves only as fast as its narrowest point; speed up anything else and nothing changes.

AI has moved the programmer's bottleneck from writing code to having good design ideas, and there is no verification loop for a design idea.

  1. Michael Nielsen Physicist, writer and researcher So certainly one thing that a lot of them seem to be bottlenecked on is now having interesting ideas and in particular having interesting design ideas.

Models we see in what they say

Our reading: their claim applies the idea without naming it. The claim is theirs; filing it here is ours.

Specialise and trade

Do what you are relatively best at and trade for the rest (comparative advantage); it holds until power or change breaks it.

Comparative advantage stops governing once the power imbalance is large enough: groups then switch into seeking to dominate instead of trading.

  1. Michael Nielsen Physicist, writer and researcher and part of it is just power, I think. Like, once there's a sufficiently large power imbalance, um, very often, not always, but very often groups of people seem to to sort of shift into this other mode where they just seek to dominate.
