## Highlights
- you make progress by successively making models followed by experiments, followed by more models, and then more experiments. And so forth.
- Without conducting experiments, building prototypes, having failures, and engaging in reality, an intelligence can have thoughts but not results. It cannot think its way to solving the world’s problems.

- there is no need to ask the question “Is the model true?”. If “truth” is to be the “whole truth” the answer must be “No”. The only question of interest is “Is the model illuminating and useful?”.
- However, at scale, all software, all laws, all processes, all theories, all constitutions are incorrect. You assess whether they are useful.
