Book Review: Elon Musk

September 13, 2023 · Original source

When SpaceX was on its last few hundred thousand dollars, and the Falcon 1 kept blowing up, and no private company had ever launched a rocket to space before, and they only had a few weeks to make Falcon 1 fly and restore investor confidence before the company went bankrupt - Elon was still putting some of his energy into planning the Falcon 5 and Falcon 9. The same thing happened with the Tesla Roadster and the Model S.

In Defense Of The Amyloid Hypothesis

August 14, 2025 · Original source

Some years ago, I worked on the guidance and navigation software for the Falcon 9 first stage landing. The early attempts failed because of annoying issues like stuck propellant valves, running out of fin hydraulic fluid, and so on. It took many tries to iron out all those issues. Meanwhile, fans and critics kept proposing that SpaceX’s fundamental approach was flawed, and suggesting entirely different approaches. Most of that criticism was pretty uninformed.
