Tesla's Autonomy Leap: Unlocking the Robotaxi Era

I ran the numbers on Tesla's robotaxi economics: 60 cents a mile in cost, roughly $100K profit per car per year, and a factory nobody else can match. Here's how it plays out.

Tesla's Robotaxi Leap: Driverless Rides Hit the Streets

Tesla put a driverless robotaxi on Austin roads using a mass-produced Model Y and cameras only. I think the manufacturing edge is what actually breaks the competition.

AI Heads to Orbit: Building Data Centers Beyond Earth's Limits

Earth's grids and water supplies can't keep up with AI's compute hunger. I think space data centers are where inference goes next - and the physics already checks out.

SpaceX's Sky-High Ambitions: The Dawn of a Trillion-Dollar Era

SpaceX went from a $30.5M check in 2002 to $350B in 2024. I break down the SpaceX IPO valuation math, Starship economics, and why space might be AI's real unlock.

Why Optimism Wins: The Secret to Building Wealth in Tech's Future

Pessimists list every reason a technology fails, then assign it zero chance of working. That mindset kept them out of EVs, rockets, and now AI. Here's why optimism in tech investing keeps winning.

The Dawn of Optional Work: AI, Robots, and Humanity's Next Leap

I think optional work is closer than most assume - maybe 10 to 20 years out. Here's what changes when jobs become a hobby, and the one trend that could undo it all.

Tesla's Secret Weapon: Turning Cars into the World's Largest AI Network

100 million parked Teslas, each running a kilowatt of inference. That's the distributed AI compute play the market hasn't priced in - and satellite internet is the missing link.

Tesla's Self-Driving Leap: Conquering Roads Worldwide

Tesla's FSD now handles 99% of miles in snow and on European streets. The tech is basically here - so I think the real fight over its global rollout is regulatory, not technical.
