Wow this was a fantastic talk. I an not a programmer or mathematician but I love playing around with cellular automata, and now I really want to check out Wolrfram Language!<br><br>As an aside I think I recognized Tim Tyler as the second questioner. His youtube channel is really cool. He hasn't had new content in years though. I hope he is doing cool stuff. His chanel was about  darwinian evolution, memetics and various replicating systems of one type or another. Fun stuff! Of course I could be wrong, but the questioner's voice really does sound like him.
