Today's post, Recognizing Intelligence was originally published on 07 November 2008. A summary (taken from the LW wiki):
Suppose we landed on another planet and found a large metal object that contained wires made of superconductors, and hundreds of tightly matched gears. Would we be able to infer the presence of an optimization process?
Discuss the post here (rather than in the comments to the original post).
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 Back Up and Ask Whether, Not Why, 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.
I really like trying to contrast intelligence as an optimization process vs. evolution. If we come to an alien planet, and we find something that is using negentropy, how do we know it isn't produced without intelligence as we understand it? I few ideas: Is it itself alive (reproducing, etc.?) Is it made of materials that require high energy well above the ambient temperatures/available energy? There's no reason life can't use metal, but it doesn't really smelt it, or make thermite, etc.
