[...] model being used is the simple SIR model first presented in my blog post Limits to Growth. The model is shown again below. There are two parameters: infection rate and recovery rate. [...]

I am thinking about making my own World Model.
I have noticed that one other interesting limit is the one of “available jobs”.
It is a moving limit, since there are the productivity increases, that happen randommely due to tech innovation. That would create a descending plateau till one man and many androids situation…. That is a trickier limit then CO2 and arable land.

My suspicion is that this model applies as well to the limit to success or plateauing commonly seen in safety programs; a typical ski slope improvement in accident rates, and then leveling off to a plateau-rate as internal/externals factors rise to counterbalance; i.e. safety reaches an acceptable level of risk or control. To move off the plateau, some systemic/culture shift is needed. Welcome your thoughts

Excellent quite easy to follow makes the thinking around causal loops quite clear.
