Thanks. I will be watching all his stuff. I hadn't watched Inventing on principle when I commented before...I came back to say - I think it's the best tech-related talk I've ever seen. Well, so much wider than just computers or programming--although mainly about that on one level--but it's about one's life, purpose, meaning in life etc. The first computery talk I've seen that seemed wise, strikingly so, not just smart, clever, cool, brilliant, innovative etc. Thank you HN!
