>But neither the NN nor the researcher will be able to give you a rule like: "F=(G m_1 m_2)/(r^2)" to explain the underlying reasons for the object-trajectory dynamics. It is not i…

>Everyone talks about extending life and eventually becoming immortal, yet no one asks what happens when we are immortal. I see the opposite picture when these discussions pop up: …

This is very important. It seems that the automation of labor is underexplored due to political and economical inertia (I know that industrial robots do somewhat improve, but they …

There was a couple of interesting threads on HN about ultrasound machines recently: https://news.ycombinator.com/item?id=13230741 https://news.ycombinator.com/item?id=13241295 I st…

I agree with the first sentence, but I'd like to note that there are practical (though weak) approximations of AIXI that preserve some of its properties, and while not turing-compl…

Actually there are at least two decades-old branches of computer science/mathematics that have formulated precise definitions of AI, and proved many theoretical results that gave w…

Meta- reinforcement learning could prove to be such breakthrough, see [1],[2]. Also next generation ASIC accelerators (Google's TPU, Nervana) can give 10x increase in NN performanc…

Looks like the "UNREAL" ( https://arxiv.org/abs/1611.05397 ), "Learning to reinforcement learn" ( https://arxiv.org/abs/1611.05763 ) and "RL^2" ( https://arxiv.org/abs/1611.02779 )…

Is he a CEO though? Wikipedia and other press articles say that Hassabis is the CEO: https://en.wikipedia.org/wiki/DeepMind and Suleyman is Chief Product Officer, the head of appli…

You have a lot of solid points, but note that Linux is currently being used by SpaceX in an even more safety-critical aerospace setting. Also note that interpreters have their plac…

Note that Facebook also has a formidable AI research group called FAIR and they are pursuing goals close to DeepMind's, while openly publishing their results and tools. There is a …

A general purpose reinforcement learning (RL) agent is a machine that can be taught to perform any task from a very wide range of tasks via sparse rewards given by a human or softw…

DeepMind looks like a hilariously wrong project to criticize because it is a true moonshot, something very different from the majority of other SV projects. If hiring hundreds of P…

The unpleasant truth is that this dystopia isn't coming out of nowhere, it is being built with our own hands. Our everyday desires, decisions, actions and inaction decide what will…

Turing test is relatively easy to pass if you creatively design your program to roleplay an irrational character. See this program https://en.wikipedia.org/wiki/Eugene_Goostman Obv…

I very much agree with this point of view. It seems to me that dry metaphysical debates (i.e. questioning the nature of these conversation models) are obscuring interesting practic…

I liked Anathem, but it is more of a philosophical work. Personally I think The Diamond Age is Stephenson's hard sci-fi masterpiece.

Hannu Rajaniemi, Ted Chiang and Neal Stephenson come to mind as hard sci-fi authors worthy of comparison to Greg Egan.

Well said. Political and intellectual elites tend to attach negative connotations to the word "utopia". Perhaps they feel that the very concept of utopia attracts undesirable atten…

I disagree. There exist examples of system displaying very non-trivial, open-ended behavior, and yet they are still not agi. A good example of this is https://arxiv.org/abs/1603.01…

Even if we relax hardware requirements, e.g. assume a Xeon+Titan X hardware, it is still a question if a viable conversational agent that uses deep learning to generate conversatio…

Am I the only one who thinks that dystopian scifi got boring a decade or two ago, while utopian scifi is an almost entirely neglected genre? I prefer a techno-optimistic point of v…

>Promising to deliver an AI that people could see as a friend is absolutely insane though. I don't see people being friends with something that couldn't complete the Turing Test Th…

... but without new Hardware there will be no new future. Just more of the same. We really need to embrace hardware more.
