Freddie deBoer has a post on what he calls "the temporal Copernican principle." He argues we shouldn't expect a singularity, apocalypse, or any other crazy event in our lifetimes. Discussing celebrity transhumanist Yuval Harari, he writes:

What I want to say to people like Yuval Harari is this. The modern human species is about 250,000 years old, give or take 50,000 years depending on who you ask. Let's hope that it keeps going for awhile - we'll be conservative and say 50,000 more years of human life. So let's just throw out 300,000 years as the span of human existence, even though it could easily be 500,000 or a million or more. Harari's lifespan, if he's lucky, will probably top out at about 100 years. So: what are the odds that Harari's lifespan overlaps with the most important period in human history, as he believes, given those numbers? That it overlaps with a particularly important period of human history at all? Even if we take the conservative estimate for the length of human existence of 300,000 years, that means Harari's likely lifespan is only about .33% of the entirety of human existence. Isn't assuming that this .33% is somehow particularly special a very bad assumption, just from the basis of probability? And shouldn't we be even more skeptical given that our basic psychology gives us every reason to overestimate the importance of our own time?

(I think there might be a math error here - 100 years out of 300,000 is 0.033%, not 0.33% - but this isn't my main objection.)

He then condemns a wide range of people, including me, for failing to understand this:

Some people who routinely violate the Temporal Copernican Principle include Harari, Eliezer Yudkowsky, Sam Altman, Francis Fukuyama, Elon Musk, Clay Shirky, Tyler Cowen, Matt Yglesias, Tom Friedman, Scott Alexander, every tech company CEO, Ray Kurzweil, Robin Hanson, and many many more. I think they should ask themselves how much of their understanding of the future ultimately stems from a deep-seated need to believe that their times are important because they think they themselves are important, or want to be.

I deny misunderstanding this. Freddie is wrong.
