I see. I wasn't asserting that you are going to do work you hate, however. I was mainly looking at the value of having a seemingly unachievable and incredibly broad goal as one's primary motivation.

I'm sure you have a much more nuanced view of how and why you are undertaking this life change, and I don't want to discourage you. Seeing as how the general consensus is that FAI is the most important thing to be doing, I think it would take a lot of effort to discourage you. I just can't help but think that there should be a primary technical interest in the problems presented by FAI motivating these kinds of decisions. If it was me, I would be confused as to what exactly I would be working on, which would be very discouraging.
