I have signed up to play an AI, and having given it quite a bit of thought as a result I think I have achieved some insight. Interestingly, one of the insights came as a result of assuming that secrecy was a necessary condition for success. That assumption led more or less directly to an approach that I think might work. I'll let you know tomorrow.

An interesting consequence of having arrived at this insight is that even if it works I won't be able to tell you what it is. Having been on the receiving end of such cageyness I know how annoying it is. But I can tell you this: the insight has a property similar to a Godel sentence or the Epimenides sentence. This insight (if indeed it works) undermines itself by being communicated. If I tell you what it is, you can correctly respond, "That will never work." And you will indeed be correct. Nonetheless, I think it has a good shot at working.

(I don't know if my insight is the same as Eliezer's, but it seems to share another interesting property: it will not be easy to put it into practice. It's not just a "trick." It will be difficult.)

I'll let you know how it goes.
