About 80% of my time at SpaceX and Tesla is dedicated to engineering and design, focusing on developing the next generation of products.

I split my time mostly between SpaceX and Tesla, and I also spend part of every week at OpenAI, typically half a day.

At Tesla, I focus on the Model 3, spending time in the design studio on aesthetics and the overall look and feel, while also reviewing engineering aspects of the car and the factory.

I pursued my interests in math and sciences relentlessly, eventually studying mechanical engineering and working in aerospace before joining Tesla.

At SpaceX, I work closely with the engineering team to improve the Falcon 9 and Dragon spacecraft, as well as develop the Mars colonial architecture.

I believe most hardware founders should be 90% focused on operational efficiency and survival, and only 10% on design innovation initially.

I spent two years at Steve Jobs' side doing a biography, and then I followed Elon Musk for years to understand his journey and share that information.

Elon Musk's productivity stems from his unique operating method, which involves deeply understanding the issues at his companies and addressing the most pressing problems weekly.

About 50% of our products focus on developing new vehicles, while the other 50% enhance legacy systems to extend their operational life.
