Did Eliezer really predict at some point that the singularity would occur in 2005? That sounds unlikely to me.

Eliezer has disavowed many of his old writings:

I’ve been online since a rather young age. You should regard anything from 2001 or earlier as having been written by a different person who also happens to be named “Eliezer Yudkowsky”. I do not share his opinions.

But re the 2005 listing, cf. the now-obsolete "Staring Into the Singularity" (2001):

I do not "project" when the Singularity will occur. I have a "target date". I would like the Singularity to occur in 2005, which I think I would have a reasonable chance of doing via AI if someone handed me a hundred million dollars a year. The Singularity Institute would like to finish up in 2008 or so.
