This request originated via recent discussions on HN, and the forming of HARC! at YC Research. I'll be around for most of the day today (though the early evening).
I personally vouch that this isn't fake. (But anyone familiar with Alan's work could tell that just from reading his comments here—who could possibly fake these?)
This is assuming the real one wouldn't have articulated anything unique and contextually valuable. (Unless you've got some sure-fire method to determine which statements are objectively so and that's what's getting confused.)
