Having seen many concerns about the low salary/skill ratio: it seems like about the same situation that I had for my graduate degree. I took half the salary for a job that was (by my estimate at the time) twice as cool as the alternatives. In that light, the position seems like quite a good deal, as most grad students don't earn that much. If you expect to experience side-benefits from this job, such as benefiting from increased rationality, or having cool stories to tell people about your interesting job, then this seems like a good deal.
