Stephen Wolfram Q&A, For Kids (and others) [December 18, 2020]

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

Questions include: Any tips on how to make nice presentations? - Why are there so many concepts in math that are not realized in the physical world? - What cryptocurrencies are you a fan of? Do you think any of them will "win big" in 2021? Any new players to watch? - Are big banks and governments trying to undermine the legitimacy of cryptocurrencies? - What do you think about China's new digital currency DCEP (e-yuan)? - The concept of a Democracy AI makes for a great sci-fi novel, but horrifying when applied to real life. - ​Is finding the shortest proof of a theorem computationally irreducible? - If you were sent into the past with one object of your choice with no return, what would you do to speed up human progress? (pick your favourite period before 20th century) - Do you think you will live forever now that genetic reprogramming has successfully reversed aging in lab grown human cells and organoids? David Sinclair and his Harvard associates have done this successfully in mice using Yamanaka's Nobel Prize winning gene factors. Also, are you currently doing anything to extend your life? - Stephen, do you have a Wolfram Spikey on the top of your Christmas tree? - Did you know any of the people involved with designing Ada Language? - ​Is there a formal proof that computational irreducibility exists? Is it possible that we will be able to predict any cellular automaton? - Is it possible to make a wire from space to earth and pull things up to space? - What will math look like in 1000 years?
