In 2015, I got a call from Elon Musk. Not something you expect to happen. What ensued was a six-month deep dive into the world of Elon and his companies and four long articles about what I found. Here they are:

Post 1: About Elon—and an intro to the whole series

Post 2: The full story with Tesla

Post 3: The full story with SpaceX

Post 4: About Elon’s secret sauce—the way he thinks

Then, in 2017, Elon started a new company, and I dove back in:

Long Neuralink piece coming out on @waitbutwhy in about a week. Difficult to dedicate the time, but existential risk is too high not to. — Elon Musk (@elonmusk) March 28, 2017

And two months later, another post:

Neuralink and the Brain’s Magical Future

Finally, three shorter articles about other corners of the Elon world:

Mini-posts on the Hyperloop and solar energy

And a post about SpaceX’s giant rocket that will take people to Mars
