This is one of the only mainstream articles I have ever seen that actually "gets the point" about just how AI is dangerous. The author of this one takes AI quite seriously, and understands that an AI can be dangerous even if it is not malicious. This puts this article miles ahead of basically every other similar piece.
The thing about this article that scores the most points with me, though, is the lack of mention of the various works of fiction that try to talk about AI. All to often, the author of this kind of article starts talking about how robots trying to kill us is just like Terminator, or starts talking about how Asimov's three laws of robotics are the kind of thing needed to deal with AI. But the author of this article very wisely avoided the pitfall of generalizing from fictional evidence, so thumbs up from me.

The article is mainly about the Centre for the Study of Existential Risk and the author's speculation about AI (and his association with Jaan Tallinn). Nothing made me really stand up and think "This is something I've never heard on Less Wrong", but it is interesting to see Existential risk and AI getting more mainstream attention, and the author reproduces tabooing in his willful avoidance of attempting to define the term "intelligence".
The comments all miss the point or reproduce cached thoughts with frustrating predictability. I think I find them to be so frustrating because these do not seem to be unintelligent people (by the standards of the internet at least; their comments have good grammar and vocabulary), but they are not really processing.
