I found his comment regarding learning to be the most insightful. It is a more developed explanation of what I have found to be an effective strategy for me:<p>> 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.<p>Without the structure of prior knowledge, I never understand or remember facts; however, when I've had the time to develop that "first principles" knowledge, I can usually grasp and understand the significance of minutiae.<p>How do you of HN learn? Is it similar?

"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."<p>Amazing.

Nice to see his sense of humor here too<p><a href="https://www.reddit.com/r/IAmA/comments/2rgsan/i_am_elon_musk_ceocto_of_a_rocket_company_ama/cnfq6yo" rel="nofollow">https://www.reddit.com/r/IAmA/comments/2rgsan/i_am_elon_musk...</a>
I am still reeling from having just learned that in Wernher Von Braun's book 'The Mars Project', it is proposed that the leader of the Martian government when it is formed shall be known as the 'Elon'.<p><a href="https://i.imgur.com/65YR89H.png" rel="nofollow">https://i.imgur.com/65YR89H.png</a>
I really like this comment<p><a href="https://www.reddit.com/r/IAmA/comments/2rgsan/i_am_elon_musk_ceocto_of_a_rocket_company_ama/cnfprcf" rel="nofollow">https://www.reddit.com/r/IAmA/comments/2rgsan/i_am_elon_musk...</a><p>Saying that he has no idea what is going to happen with the launch tomorrow, its a refreshing honesty.<p>I was also wondering on an semi unrelated note if HN had ever had AMA's from interesting people? I am not preposing that they should start happening though.
One thing I'd have liked to ask if I hadn't missed the window of opportunity would be regarding his desire to go to Mars himself. I have often wondered about the psychological effects of being effectively stranded on a barren, lifeless planet potentially for the rest of your life. On Earth, we can "get away from it all" and go to the country, go camping near a nice stream, listen to birds sing, go for a swim in the ocean, sit in a nice garden and eat our lunch, and so forth. How would one cope with the loss of all of that, not to mention also having to deal with the long-term physiological effects of a change in gravity?
In the US, up-vote for Challenger Schools (at least circa 1980's). They teach successful behaviors and are worth every penny. (Reaching and accelerating kids early is important.)
Does anyone know why Musk believes so strongly that robot overlords are a serious threat? I don't understand how wasting any time worrying about AI taking over, Terminator-style, is productive. We're not going to be developing Strong AI any time soon, so it's simply not a problem worth worrying about. And if we do, the Strong AI won't be in any position to "take over." It probably won't even want to take over. That's a very human trait, and Strong AI wouldn't be human.<p>I'm wondering whether he was tricked by someone at DeepMind, perhaps the same way people were tricked hundreds of years ago into thinking a chess-playing robot was possible.
>3.Our spacesuit design is finally coming together and will also be unveiled later this year. We are putting a lot of effort into design esthetics, not just utility. It needs to both look like a 21st century spacesuit and work well. Really difficult to achieve both.<p>I don't understand how looks are a legitimate criterion.

I live in australia and I have 4kwh of solar panels on my unoccluded WNW facing roof. My electricity grid connection charge is around $300 AUD per year (around USD 250 per year at current rates - which is about the same as my annual electricity bill since I currently feed into the grid at the wholesale rate). Given a 10 year payback time, how long will it take until a battery array with say two days headroom and a small generator is cost effective for me? Say I'm prepared to pay double that in order to mitigate market risk?
