Stephen Wolfram answers general questions from his viewers about science and technology as part of an unscripted livestream series.

Questions include: ​Who are your favourite Science fiction authors? What are your favourite stories/movies? - Why do people have emotions and feelings? How do emotions and feelings work? Happiness, anger, etc. - In the space of all possible mental states, what is the ratio of positive vs negative states? Is this a relative quantity? Does it obey certain transformations? - ​If people didn't have emotions then nothing would ever get done. - Do you think the set of emotions is finite? Is it possible evolution to bring a new kind of emotion in that set? Can we artificially create a new emotion? - Given our brains are most likely the source of our thoughts/emotions/etc. If there is a finite set of combinations of matter in the brain, could there then be a set of all possible thoughts? - What about the movie The Matrix? - What are your comments on the recent superconductor breakthrough? Is it a breakthrough? - If the resistance goes to zero, would the electron start accelerating without bound? - Why doesn't every single thought episode last forever? why does thought disappear after it arise? - How do you get your staff to get so much done, especially so much hard stuff??
