Weirdly aggressive reply.
First of all, the AI 2027 people disagree about the numbers. Lifland's median is nearer to 2031. I have a good amount of uncertainty, so I wouldn't be shocked if, say, we don't get the intelligence explosion for a decadeish.
"you've predicted a 95-trillion-fold increase in AI research capacity under a 'conservative scenario.'" is false. I was just giving that as an example of the rapid exponential growth.
So the answer, in short, is that I'm not very confident in extremely rapid growth within the next few years. I'd probably put +10% GDP growth by 2029 below 50%.
Even if future people matter .001% as much as present people, the argument for SL goes through.
Also, it just seems bizarre that the moral importance of a person would depend on when in time they exist. If someone time-traveled back from the future to the present, would it start being 100x worse for them to stub their toe?
