But seldom there have been people less persuasive than you when it comes to risks associated with artificial intelligence and the technological singularity.

I don't know if there is a persuasive argument about all these risks. The point of all this rationality-improving blogging is that when you debug your thinking, when you can follow long chains of reasoning and feel certain you haven't made a mistake, when you're free from motivated cognition - when you can look where the evidence points instead of finding evidence that points where you're looking! - then you can reason out the risks involved in recursively self-improving self-modifying goal-oriented optimizing processes.
