That will never work on any complex system that behaves chaotically, such as the weather or complex human endeavors. Tiny uncertainties in the initial conditions rapidly turn into large uncertainties in the outcomes.
Yeah, I wish more people understood that it is simply not possible to make precise long-term forecasts of chaotic systems. Whether it is weather, financial markets, etc.
It is not that we don't know yet because our models are inadequate, it's that it is unknowable.
The problem is we stupidly branded the field "chaos theory" and made it sound like bullshit so the ideas of non-linear dynamics have largely been lost on several generations at this point.
Not just chaos theory but "chaos theory" + psychedelic fractal artwork. Then the popular James Gleick book, "Chaos: making a new science" just sounds like complete bullshit and it sold a ton of copies.
I only started studying non-linear dynamics in about 2015 after first running across it in the late 90s but I literally thought it was all pseudoscience then.
Between "chaos theory", fractals and a best selling book it would be hard to frame a new scientific field as pseudoscience more than what played out.
