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: So do we live in a simulation or not? - So how do we perceive change? Why is motion possible? Why do we perceive that we can make "choices"? What does it mean to make a choice? - But every observer observes the same dimensionless constants (like the fine-structure constant), we don't have any choice about that observation. Or is 1/137 something that lies on an observable manifold of the ruliad? - What if the beautiful images of stars and galaxies really are a molecule in another universe and time is very, very slow in that universe from our view? - I always thought, what if we are like bacteria living on a bit of sand on the bottom of an alien's shoe while he rides an elevator, and what happens when the elevator stops? - Moving at the speed of thought, is there a max on how fast we can think?
