 One of the books that I've built recently is called Musk's Methods, Elon Musk, in other words, Tesla, SpaceX. I think he's one of the greatest real agile-less on the planet. He practices what I preach and what I believe is necessary, and we see how successful he is. So long story short and keeping it very simple, if we all used agile methods like Elon Musk does, I'd be happy and agile would be a good thing. I'm going to offer a free copy of that book showing how incredibly agile, but also quantitative, measuring engineering Elon Musk is in building his cars, which I drive, and his rocket ships, which I don't ride on yet.
