I recently published my FOOM-denialist rant as a comment on the "Why trust SIAI" thread. But that was two days ago. I don't much agree with what I wrote there. The singularity seems to me to be much closer now.
An LW semi-tradition I try to encourage: When one changes one's mind after a discussion, go back and add a note to the original post stating your new position and what led you to change it. Hopefully this will help us build a map of what arguments are correct and convincing.
I try to always upvote such things. Changing your mind should be a party.
