Wow, actually slightly shocked how seriously this model seems to be taken or, at least, how sticky it is. Coefficients, dynamics, number of entities involved, stationarity. There are so many unknowns and so many reasons to believe incomplete understanding could scupper predictions... I know everyone likes to believe themselves to be a good Fermi estimator. But trying to model the world beyond 2050 when the weather a month from now is a hard problem. Well, let's say it's Quixotic at best. Which makes me think the model isn't actually under discussion here, it's just all our priors about how much we fancy technology as a solution or not etc.
