They missed a great chance to call this "To Serve Man."

These are great.

I particularly like Waymo because of aggressively most of the media/talking heads wrote them off as "never going to beat Tesla" because google.

In the end, they took a fundamentally different approach at all levels of the product and won.

My list wasn't meant to exhaustive. Honestly not much of a list, just a few examples. SpaceX and Nvidia are both examples of deep technical moats, as are some of the others mentioned by commenters.

I agree with you that many moats are regulatory, but disagree that most moats are. Networks are powerful moats, customer lockin can work well, brand is a strong moat (at least for a time), speed and culture can function as moats.

Fwiw, I don't think any moat is ultimately perfect. Moats themselves are not meant to permanently stop an attacker - they are delaying tactics at best. Companies that stay ahead continuously re-invent and rebuild their differentiation and defenses.

Fair enough. I definitely should have added nvidia to the list.

Thank you.

What I love about that quote is that he knew that, some day, the cure rate would go even higher.

Thank you. I've only ever had bad luck creating Wikipedia entries, though it's been a while.

Thank you.

Thank you so much. He was.

Thank you.

My sister is an incredible write and he was a perfect subject.

Thank you.

I don't fully understand how he did it. I know he took a lot from the line in the Talmud that said "whoever saves a life, it is considered as if he saved an entire world."

My mom says that his baseline was incredibly high and that he was incredibly resilient. He also had a big rebellious streak, an analytical mind, and endless compassion.
