I agree, this is a ridiculous overstatement of the importance of software engineering. A renaissance man equivalent of today would have to be proficient (at least) in physics, chemistry (and mathematics naturally), (electrical) engineering, programming and to some extent even law. I don't know anyone who would fulfill these requirements.

Yes. And even if we limit the scope to "hacker" (since the blog is called "Singularity Hacker"), the lack of any hardware skills on the list seems a rather glaring omission.
