An aspired rationalist ought to be less gullible and able to spot a hoax like that. Did you feel any sense of confusion when reading it and looking at the picture?
I first read that article a while ago, and was taken in until I read some other articles on the site. It does sound plausible to me that such a robot might be built someday and go wrong in a similar fashion.
I'm neither upvoting nor downvoting the OP because I think the article is interesting a) as a test of rationality/skepticism, and b) as a simple expression of Friendly AI concepts that are worth discussing, as a thought experiment at least.
Since it's not made obvious in the title or body of the post, maybe this comment would benefit from rot13? Just a suggestion.
I read your comment before I clicked on the link, so I didn't get the chance to spot the hoax for myself.

Might be a nice story to point out to people who think "friendly" is easy.
