Are you suggesting that every time he speaks, we should be silent and accept his words as absolute truth, even when we believe he is wrong? Seriously? What a low argument. I prefer he responds, at least he knows how to debate, even though I don't share his dirty debate tactics. Principally, just to continue embodying the role of "ktimesg" here, I suspect you are talking to him seeking whatever you wanted to talk about with Retiredcoder, and he denied you, and now you are flattering him. I'm not going to ignore him if I don't want to. After all, this is a forum to discuss ideas, not Wikipedia. As practice, answer this: in what do you think he is right, or in what did I fail? Without deviating from the direct topic and with arguments, without generalizing? I believe you won't be able to do it without falling into some kind of fallacy. Give us your technical opinion on why you think probabilistic search is unfeasible.
