the references to have a read through are not science fiction, but are system modelling studies done in the 70s:

there's lots of people who dismiss this as "doom and gloom". it's worth getting hold of the books and reading through it, and making up your own mind. do you think the modelling assumptions seem reasonable? even if some of the parameters seem difficult to estimate from observed real world data, do you reckon the overall system dynamics behaviour of predicted "overshoot and collapse" seems plausible, even if the timing may be very difficult to predict?
I'm reading Donella Meadows' Thinking in Systems right now which I think is a good overview of this line of reasoning. Of course models are idealized, but they're also one of the best ways to understand complex systems. The human brain does something very similar in forming intuitions about the world, but we should recognize that in order to make a better model we will have to make one in silico. Another interesting approach is agent-based modeling, which explores how the decisions of agents with limited information can create emergent patterns.
I'm guessing you're using an analog to "past performance doesn't predict future performance" which is true.
However, seeing as the default likelihood of predicting any future with certainty is zero, a track record of a model of being entirely unable to predict the future at all does very much indicate that such a model will continue to fail, more often than not.
Predicting the future based on what has happened is not reliable, but predicting the future based on models that have predicted the future before should be reliable, if the models themselves are based in reality.
how did everyone’s model of 2019-2021 pan out on any given metric? Even if they successfully predicted that same metric correctly for the last 100 years.
I guess weather/climate models stay somewhat consistent. But they also don’t predict very far forward.
Ok so assuming you had a system that you could give it a bunch of inputs and it would predict what the results from those would be 10 years out, and it was correct 60% of the time from past observations, and you had run it on thousands of simulations (this is obviously a hypothetical) is it then your contention that if you gave it inputs from our current inputs and had it predict results ten years from now that those predictions would not have a 60% chance of being correct?
I mean sure, since there is such a thing as an inductive gap in theory, but it seems to me from your statement that you think it to be an insurmountable obstacle in practice as well?
It's obvious enough. Conditions change. Systems are dynamic. A model of human society that "works" for the next 10 years may not work for the subsequent 10 years.
