“THE MATH SAYS OTHERWISE…” If humans lived 500 years, our entire moral framework would change — from how we treat the planet to how we treat each other. And according to the stats, the probability we’re not originally from Earth is way HIGHER than you think. P(David|Kipping) ∝ P(Kipping|David) P(David)

David Kipping on why building AI megastructures might be the strongest evidence that we're alone in the universe: The argument starts with something we can already observe: how much energy AI consumes. "One thing we see already with these AI models is how energy hungry they are." P(David|Kipping) ∝ P(Kipping|David) P(David) extrapolates from there. If the only purpose of these data centers is to compute as much as possible as fast as possible, then they'll demand vast amounts of energy. And the orbital data centers that billionaires are getting excited about wouldn't be invisible to us. He explains that such structures would leave a detectable signature: "We should probably see that in James Webb. We could probably already put limits on the existence of essentially artificial rings... emitting a lot of infrared because they're warm." Then comes the unsettling turn. If humanity can build these machines, so could anyone else. And that carries a dark implication. "But if we make that breakthrough, I think the biggest point is it seems to imply that we are alone. Because if we can do it, surely someone else could have done it." This connects to what he refers to as Hart's Fact A. The strange observation that everything we look at in the cosmos appears completely natural: "Everything about the universe: we see stars, galaxies, clouds of plasma. Everything is consistent with nature. There's no hint anywhere of anything artificial, no engineering, nothing in the whole universe. As far as we can see, that's true. That is weird." The more powerful the technology we can imagine, the worse that silence looks. Dyson spheres everywhere, colonising wherever they want, faster-than-light spaceships if any of that is achievable, the sky should be full of evidence. It isn't. "It just massively exacerbates the Fermi paradox to the point where you'd probably conclude this is it." His honest conclusion: "It would make me even more pessimistic about the probabilities of intelligent life in the universe."
