Can you explain what a “differentiable” decision theory is? I understand, for instance, maximizing expected value (and taking a derivative to get a maximum), but I don’t understand how the concept of maximizing expected value could itself be made into a derivative.

Edit: Seems like a “differentiable theory” is just one that can be framed in terms of an optimization problem that can be solved by gradient descent. Is that right?

Couple questions:

1. Where does the name come from?

2. I’ve seen a lot of startups with the business model of serving other startups. These remind me a lot of derivatives in the stock market in terms of the “risk” of their business model, and there have been instances of companies having to pivot when the economy goes down (i.e. Brex)… Do you have a contingency plan for this?
