20: What is the probability that this is the ultimate base layer of reality?

Eliezer gave the joke answer to this question, because this is something that seems impossible to know.

However, I myself assign a significant probability that this is not the base level of reality. Theuncertainfuture.com tells me that I assign a 99% probability of AI by 2070 and it starts approaching .99 before 2070. So why would I be likely to be living as an original human circa 2000 when transhumans will be running ancestor simulations? I suppose it's possible that transhumans won't run ancestor simulations, but I would want to run ancestor simulations, for my merged transhuman mind to be able to assimilate the knowledge of running a human consciousness of myself through interesting points in human history.

The zero one infinity rule also makes it seem more unlikely this is the base level of reality. http://catb.org/jargon/html/Z/Zero-One-Infinity-Rule.html

It seems rather convenient that I am living in the most interesting period in human history. Not to mention I have a lifestyle in the top 1% of all humans living today.

I believe this is a minority viewpoint here, so my rationalist calculus is probably wrong. Why?

In my posts, I've argued that indexical uncertainty like this shouldn't be represented using probabilities. Instead, I suggest that you consider yourself to be all of the many copies of you, i.e., both the ones in the ancestor simulations and the one in 2010, making decisions for all of them. Depending on your preferences, you might consider the consequences of the decisions of the copy in 2010 to be the most important and far-reaching, and therefore act mostly as if that was the only copy.

BTW, I agree with this.
