This blog contains a lot of material that is very weird. A natural question is: why write about such weird things? Many of the situations I’ve considered or problems I’ve written about involve improbable hypotheticals. We probably won’t ever have a powerful utility maximizer which we must provide a precisely defined utility function, for example. Why not focus on designing systems that are likely to actually get built?

The reason should not be so unfamiliar to a mainstream academic: though these problems may be too simple to be directly applicable, thinking about them sheds light on fundamental philosophical and mathematical issues. The heuristic is something like: where there are simple, fundamental problems on which it is possible to make progress, you should do it, even if you can’t see exactly why or how that progress will be useful.
