The big names of deep learning have all taken a vocal stance against the recent end-of-the-world punditry (most notably Yann LeCun and Andrew Ng). Also notable: roboticist Rodney Brooks http://www.rethinkrobotics.com/artificial-intelligence-tool-...
You are quite mistaken. He leads the applied AI team there, and has significant history in research.
The question is what Michael Jordan thinks of the "concept of the singularity", and then he dismisses it out of hand.
Crucially, he does this after confessing that no one in his social circle has talked about this issue with him, and without saying anything about what form of Singularity he is dismissing.
I mention this, because oftentimes I see people appealing to authority, quoting them on the issue and the authority in question is not even talking about the same issue!
I worry that my credence in all this superintelligence stuff only stems from familiarity with the arguments and the complete inability of people to engage with the actual argument. Some of the 'rebuttals' in this comments section have answers in Sam's article for crying out loud!
People hear "machine learning" and they think it is about machines that know how to think. Machine learning is actually just optimization of high dimensional functions. If this language were used it wouldn't sound as sexy, but no one would think machines are going to take over the world.
AI isn't magic. It's really just clever search techniques and mathematical optimization.
What's your point? Nobody said it's magic. The fact that it isn't magic (and that its tremendous complexity far surpasses our current ability to understand it) supports the notion that it won't suddenly spring into existence. If we placed some primordial sludge in a petrie dish overnight, we wouldn't worry that a sentient creature will have materialized. And if we program a computer to optimize numerical functions, there is just as little evidence (perhaps less), to suggest that the computer will somehow gain sentience.
It's an entertaining society and endlessly fun to read, but still complete fiction based on internal brain states of individuals and not necessarily based on real world interactions.
