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 sand form near the sea? - Is grammar invented or discovered? - ​I believe there exists a 13 letter language from a pacific island. Do you think a 10 letter language would be useful since every word would also be a base 10 number? - ​How can a natural programming language replace older concrete programming languages, would it be fuzzy or like a predictor language? since often natural language can be interpreted differently? - What would be your thoughts on Languages from the perspective of the category theory? It seems like Category theory encompasses all of Math. - What limitations does Wolfram Alpha have currently, and what methods are you exploring to address those limitations?
