Is anyone curious what these "other things" were?
How are we supposed to know what this other things Satoshi claimed to have moved on to were or are when he did not say? At least, I believe no body in the bitcoin community is a magician, so except he had said it, there is no way we can know.
I think Satoshi has to be given the prestigious award of the most secretive person in the entire whole world, I've learnt from this man or group of persons that not every thing a person does should he stick around and take glory for it, sometimes, it pays more to simply create something very good that many would benefit from and then simply take away from the limelight, and allow people to enjoy your creation without knowing who to return glory or thanks to but just the name you left behind.
So whatever Satoshi moved on to, I really hope he is alive, healthy and living his best life with this family and friends.
