Elon Musk kilkanaście godzin temu popełnił Reditowe Ask Me Anything  (ograniczona w czasie publiczna sesja pytań i odpowiedzi). Poniżej zamieszczam, w orginale, najciekawsze według mnie pytania i/lub odpowiedzi. Źródło. #1. #2. #3. #4. #5. #6. #7. #8. #9. #10.

1. Q: […] My question: You seem to have had to deal with a tremendous amount of adversity in a few of your ventures. Do you have any advice for those dealing with seemingly insurmountable adversity?
   A: There is a great quote by Churchill: „If you’re going through hell, keep going.”
2. Q: „Why you aren’t using more advanced technical solutions based on a planes but simple one like rockets?” (przypis – streściłem dłuższe bardziej wysublimowane pytanie)
   A: If you want to get to orbit or beyond, go with pure rockets. It is not like Von Braun and Korolev didn’t know about airplanes and they were really smart dudes.
3. Q: […] you’ve stated that you estimate a 50% probability of success with the attempted landing on the automated spaceport drone ship tomorrow. Can you discuss the factors that were considered to make that estimation? […]
   A: I pretty much made that up. I have no idea :) […]
   Follow-up Q: Can you help me with Kerbal Space Program? (przypis – gra o zarządzaniu agencją a la NASA robiona przez fanów podboju kosmosu, dowcipnisie)
4. Q: I’m a teacher, and I always wonder what I can do to help my students achieve big things. What’s something your teachers did for you while you were in school that helped to encourage your ideas and thinking? Or, if they didn’t, what’s something they could have done better? thanks!
   A: The best teacher I ever had was my elementary school principal. Our math teacher quit for some reason and he decided to sub in himself for math and accelerate the syllabus by a year. We had to work like the house was on fire for the first half of the lesson and do extra homework, but then we got to hear stories of when he was a soldier in WWII. If you didn’t do the work, you didn’t get to hear the stories. Everybody did the work.
5. Q: What daily habit do you believe has the largest positive impact on your life?
   A: Showering
6. Q: tl;dr: How do you learn so much so fast? Lots of people read books and talk to other smart people, but you’ve taken it to a whole new level. […]
   A: I do kinda feel like my head is full! My context switching penalty (przypis -„koszt” przeskakiwania między różnymi zadaniami, z agile dev) is high and my process isolation (skupienie się tylko na jednym procesie, z programowania) is not what it used to be. Frankly, though, I think most people can learn a lot more than they think they can. They sell themselves short without trying. One bit of advice: it is important to view knowledge as sort of a semantic tree — make sure you understand the fundamental principles, ie the trunk and big branches, before you get into the leaves/details or there is nothing for them to hang on to.
7. Q: […] A friend of mine is all paranoid about the computer singularity, and used your name as a source of his paranoia. Don’t you think it could all be a bunch of hype?
   A: The timeframe is not immediate, but we should be concerned. There needs to be a lot more work on AI safety. And, with all due respect to the Roomba dude, that is not a concern https://www.youtube.com/watch?v=Of2HU3LGdbo (śmieszny film z kotem od Muska, jego zespół PR odrobił robotę – przypis)
8. Q: 1) What is your favorite airplane? 2) What is your favorite video game? 3) What is your favorite food? 4) If you consume alcohol, what is your favorite alcoholic drink?
   A: 1) SR-71 2) Hard to pick a favorite. I tend to like FPS with a story, like Bioshock, Fallout or Mass Effect, but was also a big fan of Civ and Warcraft. (przypis – zna nazwy gier!) 3) French and BBQ 4) Whiskey
9. Q: […]Have you heard of/played Kerbal Space Program?[…]
   Follow-up Q: What do you think SpaceX uses for testing software?
   A: Kerbal Space Program!
10. Q: Nice to see that you are doing things the Kerbal way. (przypis – w tym znaczeniu bardzo prosto)
    A: Kerbal is awesome!
