Until about 2006 EY was working on papers like CEV and working on designs for FAI which he has now discarded as being wrong for the most part. He then went on a long period of blogging on Overcoming Bias and LessWrong and is now working on a book on rationality as his stated main focus. If this be accurate I would ask how does this make sense from someone who has made such a big deal about FAI, its importance, being first to make AI and ensure it is FAI?

I know! It's a Xanatos Gambit!
