Yes, what "AGI" refers to on LW is typically something far more powerful than what you describe. And yes, this causes a lot of confusion from time to time, when people confuse it with artificial intelligence in general (I've made this error more than once), which is one reason I often try to talk about "superhuman optimizers" rather than "AIs" in the LW context. (I often fail.)
Today's post, Above-Average AI Scientists was originally published on 28 September 2008. A summary (taken from the LW wiki):

This post is part of the Rerunning the Sequences series, where we'll be going through Eliezer Yudkowsky's old posts in order so that people who are interested can (re-)read and discuss them. The previous post was Competent Elites, and you can use the sequence_reruns tag or rss feed to follow the rest of the series.
Sequence reruns are a community-driven effort. You can participate by re-reading the sequence post, discussing it here, posting the next day's sequence reruns post, or summarizing forthcoming articles on the wiki. Go here for more details, or to have meta discussions about the Rerunning the Sequences series.
