Right now we're still gathering the initial team, doing market research, experimentally testing our success at teaching rationality, and so on. So one reason for the lack of information about what Rationality Org will look like is that we don't have that information yet. And I'm not sure when we'll have it.
Yesterday I sat down with Lukeprog for a few hours and we produced this ten-page interview for the Singularity Institute blog. This interview contains information about the Singularity Institute's technical research program and recent staff changes that hasn't been announced anywhere else! We hope you find it informative.
