Stephen Wolfram answers general questions from his viewers about science and technology as part of an unscripted livestream series, also available on YouTube here: https://wolfr.am/youtube-sw-qa

Questions include: How does the Bloomberg Terminal work? - Did that guy find his satellite by the way? or did it just float off into space or lose power? - What are Feynman Diagrams? - How do holograms work and why don't we have more holographic technology? - Have you read "The Deep Learning Revolution:" (2018, MIT Press) by Terrence J. Sejnowski? - How closely do you follow the field of AI? - Is it possible, with quantum tunnelling, that eventually, long in the future, the universe will have mostly, or even a large proportion of, 'iron stars'? How would iron stars affect planets with iron cores orbiting these stars?
