Do you have a favorite sandwich?

I don't often eat sandwiches, but when I do, I make what my family calls "awesome sandwiches". They are a kind of spicy Reuben: pastrami with a mixture of Dijon mustard, Russian dressing and curry powder. I also like panini. Also, savory buckwheat crêpes, Breton style (not technically sandwiches, but best thing ever).

This was our culinary interlude.

How would you rank the real challenges/bottlenecks in engineering an intelligent 'OS' like the one demonstrated in the movie 'Her' ... given current challenges in audio processing, NLP, cognitive computing, machine learning, transfer learning, conversational AI, affective…

Something like the intelligent agent in "Her" is totally out of reach of current technology. We will need to invent new concepts, new principles, new paradigms, new algorithms.

The agent in Her has a deep understanding of human behavior and human nature. It's going to take quite a while before we build machines that can do that.

I think that a major component we are missing is an engine (or a paradigm) that can learn to represent and understand the world, in ways that would allow it to predict what the world is going to look like following an event, an action, or the mere passage of time. Our brains are very good at learning to model the world and making predictions (or simulations). This may be what gives us 'common sense'.

If I say "John is walking out the door", we build a mental picture of the scene that allows us to say that John is no-longer in the room, that we are probably seeing his back, that we are in a room with a door, and that "walking out the door" doesn't mean the same thing as "walking out the dog".

That's really funny, and nicely drawn. It makes me look thinner than I am too ;-) I'm just slightly worried about Bender's nasty look. He is clearly not interested in ConvNets. He is probably thinking "I'm 30‰ ConvNet" or "kill…

I'm just slightly worried about Bender's nasty look. He is clearly not interested in ConvNets. He is probably thinking "I'm 30‰ ConvNet" or "kill all humans" Either that or he is looking for the bar.
