Note that compared to the previous argument, the a prior odds on being the most influential person is now 1e-10, so our earliness essentially increases our belief that we are the most influential by something like 1e28. But of course a 1-in-a-100 billion prior is still pretty low, and you don’t think our evidence is sufficiently strong to signficantly reduce it.
The argument is not about whether Will is the most influential person ever, but about whether our century has the best per person influence. With population of 10 billion+ (78 billion alive now, plus growth and turnover for the rest of the century), it’s more like 1 in 13 people so far alive today if you buy the 100 billion humans thus far population figure (I have qualms about other hominids, etc, but still the prior gets quite high given A1, and A1 is too low).
I should also point out that, if I’ve understood your position correctly Carl, I agree with you. Given my second argument, that a prior we have something like 1 in a trillion odds of being the most influential, I don’t think we should end up concluding much about this.
Most importantly, this is because whether or not I am the most influential person is not actually relevant decision making question.
But even aside from this I have a lot more information about the world than just a prior odds. For instance, any long-termist has information about their wealth and education which would make them fairly exceptional compared to the average human that has ever lived. They also have reasonable evidence about existential risk this century and plausible (for some loose definition of plausible) ways to influence this. At the end of the day each of us still has low odds of being the most influential person ever, but perhaps with odds more in the 1 in 10 million range, rather than 1 in a trillion.
(It appears you dropped a closing parenthesis in this comment)
I will now consider everything that Carl writes henceforth to be in a parenthetical.
In his first comment Will says he prefers to frame it as “influential people” rather than “influential times”. In particular if you read his article (rather than the blog post), then in the end of section 5 he says he thinks it is plausible that the most influential people may live within the next few thousand years, so I don’t his odds that this century is the most influential can be very low (at a guess, one in a thousand?). I might be wrong though; I’d be very curious to know what Will’s prior is that the most influential person will be alive this century.
It’s the time when people are most influential per person or per resource.
