Why? What's "silly" about it? I think the article does the best you can at predicting that far out, which is saying which futures are incompatible with each other. I find meaning in thinking about the future and I like seeing it be done well.
It doesn’t make any sense to graph something like gdp or economic output on a scale of thousands of years. The world looks nothing like it did 2000 years ago, and 2000 years from now, by the authors own admission, it will look entirely different.
IMO the graphs the author uses are like graphing something like baking a cake. Y axis is “how much is this thing a cake” and x axis is time. It’s zero pretty much the whole time, then you stick it in the oven and it rapidly becomes a cake. Funny thought experiment I guess, but it provides no value.
Science fiction would never exist with this attitude and we can read early science fiction and see that much of it was in fact quite correct. The speculation gets us to thinking about what is coming and what we can do to make it better.
