SIMPLE PPE COST-EFFECTIVENESS MODEL

I thought that the old cost-effective model relied too much on a tower of fake assumptions, and I wanted something that was simpler and easier to intuit.

This new model assumes that there's a certain amount of x-risk that's addressable with PPE alone. This risk exists because we either 1) don't have enough effective PPE in stock to protect everyone quickly, 2) we can't produce enough effective PPE to protect everyone quickly, or 3) both.

The amount of this PPE-addressable x-risk that's *actually* addressed is a function of two things: how much we increase PPE stocks, and how much we increase PPE production capacity. To capture this, I use an OR function: 100% of the PPE-addressable risk has been reduced when:
  - We have 8B units of PPE OR
  - We're able to produce 8B units of PPE per day

// WIP: don't take these numbers literally

/*
BETS COST-EFFECTIVENESS MODEL

This model is meant to estimate the rough cost-effectiveness of different BETS interventions. Broadly, it looks at two paths for these interventions to reduce bio x-risk:
1. Lowering the chance that an x-risk-level infectious disease is able to spread sustainably (particularly before initial detection)
2. Improving humanity's ability to weather an x-risk-level infectious disease by reducing vital worker likelihood of infection, either in workplaces (wearing PPE) or safe zones (not wearing PPE)
