Regarding your question, I don't see theoretical reasons why one shouldn't be making deals like that (assuming one can and would stick to them etc). I'm not sure which decision theory to apply to them though.

The Moral Parliament idea generally has a problem regarding time. If it is thought of as making decisions for the next action (or other bounded time period), with new distribution of votes etc when the next choice comes up, then there are intertemporal swaps (and thus pareto improvements according t...(read more)

This is a good idea, though not a new one. Others have abandoned the idea of a formal system for this on the grounds that:

1) It may be illegal 2) Quite a few people think it is illegal or morally dubious (whether or not it is actually illegal or immoral)

It would be insane to proceed with this wi...(read more)

This is a really nice and useful article. I particularly like the list of problems AI experts assumed would be AI-complete, but turned out not to be.

I'd add that if we are trying to reach the conclusion that "we should be more worried about non-general intelligences than we currently are", then y...(read more)

Thanks for bringing this up Luke. I think the term 'friendly AI' has become something of an albatross around our necks as it can't be taken seriously by people who take themselves seriously. This leaves people studying this area without a usable name for what they are doing. For example, I talk with...(read more)

This is quite possibly the best LW comment I've ever read. An excellent point with a really concise explanation. In fact it is one of the most interesting points I've seen within Kolmogorov complexity too. Well done on independently deriving the result!

Without good ways to overcome selection bias, it is unclear that data like this can provide any evidence of outsized impact of unconventional approaches. I would expect a list of achievements as impressive as the above whether or not there was any correlation between the two.


You are completely right that there is a somewhat illicit factor-of-1000 intuition pump in a certain direction in the normal problem specification, which makes it a bit one-sided. Will McAskill and I had half-written a paper on this and related points regarding decision-theoretic uncertainty ...(read more)

Regarding (2), this is a particularly clean way to do it (with some results of my old simulations too).

We can't use the universal prior in practice unless physics contains harnessable non-recursive processes. However, this is exactly the situation in which the universal prior doesn't always work. Thus, one source of the 'magic' is through allowing us to have access to higher levels of computation tha...(read more)
