Ok, I took the bait, who is this AI Guru? His name is Danny Lange, who has published his latest paper in 1999, which means ages ago in AI time. Keep it real! This kind of hype is not worth it.
That doesn't say anything about his abilities, but I'm not here to judge the person but the article.
I think trying to find out "who he is" and his accomplishments is actually bad: Let's just concentrate on the article. It doesn't get better or worse if I were to know anything more about the guy. Everything that we are here to talk about is there - I really don't understand some of the comments where people try to discuss the person instead of the content. Neither attacking the person or elevating him are of any help.
