Specifically, Tetlock's project opens with key issues of scope about what to even try to forecast. Based on his previous work in expert prediction, he concluded that geopolitics is sufficiently chaotic to be impossible to predict 10 years out. So while he did a lot of work on forecasting, it is generally focused on the next year or to.
Which means that Tetlock agrees that we can't predict 10 years out.
But I do not think I painted much of a picture of Tetlock's results.
I read the article as concluding: let's stop predicting, it does not work. Let's start building. (After stating we cannot predict this, and we cannot predict that.)
And I think Tetlock"s result contradict that, as I said. Sometimes and under certain circumstances we can predict quite well.
In other words, you cannot use information from today to improve predictions beyond long-term statistical generalities.
But that doesn't mean the prediction is useless, only that it has great uncertainty.
