Stephen Wolfram Q&A, For Kids (and others) [April 16, 2021]

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

Questions include: What are some of the NKS implications for medicine? - What's the minimum amount of DNA pairs that is not "obviously basic" and could perform universal computation? Would this be the lower bound for some heuristic of complexity of life? - Is there any fundamental computational boundary to a super-intelligent AI doctor capable of connecting all the medical specialties? - Why are we are not prioritizing research in longevity? - What makes HeLa cells "immortal" and how common are they in humans? Or was Henrietta the only person ever to have "immortal" cells? Do other species have cells like HeLa cells? - Why can't we reproduce cell membranes? Aren't they made up of proteins? - How do you organize/prepare for a talk? - How many hours should a scientist work per day? - Why isn't nuclear power used more and is there a way to make it smaller and safer so that it can be used like portable power generators? -  What do you feel is the place of philosophy in modern science?
