Fair point -- I actually wasn't 100% convinced myself it fits here... Reason for posting it anyway was that (a) it somehow reminded me of the omega/2-boxes problem (i.e., the paradoxal way how present and past seem to influence each other), (b) Hans Moravec work touches on so many of the AI/transhumanist themes common in LW and (c) I found it such a clever observation that I thought people here would appreciate.

Not sure if that's enough reason, but that's how it went.
