Crossposted from the AI Alignment Forum. May contain more technical jargon than usual.

Edit 30/5/19: An updated version is on arXiv. I now feel comfortable with it being cited. The key changes:

• The Title. I suspect the agent is unambitious for its entire lifetime, but the title says "asymptotically" because that's what I've shown formally. Indeed, I suspect the agent is benign for its entire lifetime, but the title says "unambitious" because that's what I've shown formally. (See the section "Concerns with Task-Completion" for an informal argument going from unambitious -> benign).
• The Useless Computation Assumption. I've made it a slightly stronger assumption. The original version is technically correct, but setting is tricky if the weak version of the assumption is true but the strong version isn't. This stronger assumption also simplifies the argument.
• The Prior. Rather than having to do with the description length of the Turing machine simulating the environment, it has to do with the number of states in the Turing machine. This was in response to Paul's point that the finite-time behavior of the original version is really weird. This also makes the Natural Prior Assumption (now called the No Grue Assumption) a bit easier to assess.

Original Post:

We present an algorithm, then show (given four assumptions) that in the limit, it is human-level intelligent and benign.

Will MacAskill has commented that in the seminar room, he is a consequentialist, but for decision-making, he takes seriously the lack of a philosophical consensus. I believe that what is here is correct, but in the absence of feedback from the Alignment Forum, I don't yet feel comfortable posting it to a place (like arXiv) where it can get cited and enter the academic record. We have submitted it to IJCAI, but we can edit or revoke it before it is printed.

I will distribute at least min($365, number of comments *$15) in prizes by April 1st (via venmo if possible, or else Amazon gift cards, or a donation on their behalf if they prefer) to the authors of the comments here, according to the comments' quality. If one commenter finds an error, and another commenter tinkers with the setup or tinkers with the assumptions in order to correct it, then I expect both comments will receive a similar prize (if those comments are at the level of prize-winning, and neither person is me). If others would like to donate to the prize pool, I'll provide a comment that you can reply to.

To organize the conversation, I'll start some comment threads below:

• Positive feedback
• General Concerns/Confusions
• Minor Concerns
• Concerns with Assumption 1
• Concerns with Assumption 2
• Concerns with Assumption 3
• Concerns with Assumption 4
• Concerns with "the box"
• Adding to the prize pool
