There is an anthropic line of reasoning over Everettian branch universes where you can actually expect these types of highly unlikely events to happen more often than chance alone would predict if they promote futures with more Born-rule weighted observer-moments.
- thecopy 3y agoThis sounds "right" but i have no idea what you mean.
- rvcdbn 3y agoSee my response to the other comment. I think I got this idea either from David Deutsch or Frank Tipler, I forget exactly which book.
- fouronnes3 3y agoWhat on earth does this mean?
- rvcdbn 3y agoPlease don't take this as dismissive, but I really think ChatGPT does a better job at explaining this than I can do. Here's what I got: https://chat.openai.com/share/c1c779c7-3b5f-4ea7-a864-38561d679e93 https://chat.openai.com/share/c1c779c7-3b5f-4ea7-a864-38561d... The response you posted seems to be referring to various concepts from theoretical physics and philosophy, specifically the ideas of the Everettian interpretation of quantum mechanics, anthropic reasoning, and the Born rule. Let's break these down: Everettian interpretation of quantum mechanics: Also known as the Many-Worlds interpretation, it suggests that all possible alternate histories and futures are real, each representing an actual "world" or "universe". In layman's terms, it's the idea that there could be countless parallel universes where every possible outcome of an event happens. Anthropic reasoning: This is a philosophical consideration that observations of the universe must be compatible with the conscious and sapient life that observes it. In other words, our ability to exist and observe influences how we should interpret the universe. Born rule: In quantum mechanics, the Born rule is a statistical law that connects the mathematical formalism of quantum theory to experimental observations. It provides the probability that a measurement on a quantum system will yield a given result. The responder seems to suggest that in a universe with many possible futures (as the Everettian interpretation would suggest), we are more likely to observe "black swan" events that lead to more possible futures. The idea here is that if an event significantly increases the number of possible futures (like a breakthrough that extends human lifespan), then it effectively increases the number of "observer-moments". In other words, more possibilities for observers to exist and make observations. According to anthropic reasoning, this could make these events more likely to occur than pure chance would predict, because we're only able to observe futures in which we exist. This line of reasoning is highly speculative and philosophical in nature, touching on deep and unresolved questions in physics and philosophy. It's an interesting thought experiment, but it's important to note that this isn't widely accepted or proven in the scientific community as of my knowledge cutoff in September 2021.

- rvcdbn 3y agoI said "there is a line of reasoning...", I didn't say I fully believe it. It definitely depends on a lot of pretty speculative ideas. I'm happy to discuss this further if you'd like to point out exactly which parts of the argument you object to. EDIT: I continue the conversation with ChatGPT to try to poke holes in the argument if you’re interested: https://chat.openai.com/share/19871222-9810-4a25-9604-8e690b8c3d94 https://chat.openai.com/share/19871222-9810-4a25-9604-8e690b...
- marcosdumay 3y agoJust to add on the "nonsense" line. Using the antropic principle to talk about the future is completely absurd. There is a huge amount of what I think in unawarded debate about applying it to the past (IMO, it's very clear where it should be used), but applying it to the future is completely against any kind of logic.
- rvcdbn 3y agoWhy? If the argument works at this point in time when reflecting on our history what makes it stop working for future observers who reflect on their histories? It can certainly lead you to some pretty wacky-sounding conclusions (looking at you Frank Tipler) but I can’t see why it’s obviously wrong for future observers to deploy it in just the same was as we do.
- marcosdumay 3y agoNo, it's pure bullshit. You can't apply conditional probabilities to unbias some result if you don't know if the condition holds or not. You can invent some fiction where some future people apply it. You just can't pretend that there is any realism on it.
- rvcdbn 3y agoSo you’re saying that that line of reasoning depends on people existing in the future and thinking about the same kinds of things we do now in the same kinds of ways (at least wrt this particular argument). I can see how that is not guaranteed, especially far into the future where it might become difficult to understand what qualifies as an observer-moment. It is certainly speculative.
- marcosdumay 3y agoIt's not speculative. It's completely invalid, and any conclusion you take from it is circular.
