Is this thing actually being used for policy decisions?
Given the complexity, poor language/framework choice (should have used either Rust or Tensorflow), bad code design, and unclear determination of the parameters (especially the fact they don't seem to be estimated from real data with Bayesian inference, or if they are they didn't release that), as well as the ludicrous CPU and RAM usage making it impossible for most people to run it and thus check it, it doesn't seem like it has any chance of actually being a good model.
If this is the state of the art for the most important statistical modelling project in the world, we are in the dark ages.
