So I give you the geopolitical answer, but I think, okay, here are some projects I think I can share. So Oppenheimer was hugely successful and complicated, right? Where it's like, it's three-dimensional to the point of entertainment. It's not Pravda. I think there's a very powerful story in Hyman Rickover and the birth of the nuclear navy. And we talked a little bit about him, But, you know, what I love about Rickover is he was born in a shuttle in Poland, came over at the age of six.

One of these near, almost near-miss stories where they were on Ellis Island. When you get to Ellis Island, you have 10 days for someone to come pick you up. And so his mother sent a telegram. It gave someone money to send a telegram to the father who was already here to come get them. The guy pocketed the money for the telegram. On day 10, someone happens to arrive that they know from the old world who then runs out, gets the father to claim them, buys them one extra day.
- 50:45
So on day 11, they get picked up. But you had this near miss where we almost didn't have Rickover. But Rickover was a notoriously difficult personality. He was a five foot two, short guy. In World War II, he drove a coal ship. It was not a prestigious post. But after World War II, he was sent to Oak Ridge at the vestiges of the Manhattan Project. And he was inspired. He had this idea of putting nuclear power inside of the submarines.

Because before then, submarines sucked. They could go underwater for like an hour. They were diesel-powered. They were loud. They were basically surface ships that could occasionally submerge. And after that, they became really exquisite. And I think he built the first one in, like, five years, six years, the Nautilus. But the Navy didn't want him to succeed. Not only did Oppenheimer think it was a stupid idea, the Navy did, too.
- 51:32
His first office was a women's restroom. I kid you not, you know, it's like, how can we humiliate this guy to quit? And he just kept going. And what I think is interesting when you look at his memoirs, Like, it's not that he was immune to the humiliation. He felt every slight and insult. He documented them, but somehow he was able to channel that into something he was going to push through and still succeed despite that.

Zumwalt, who was the chief of naval operations, the senior most uniformed person in the Navy, said, the Navy has three enemies, the Soviet Union, the Air Force, and Hyman Rickover, the zone admiral. the other thing that I think fits very closely with 18 Theses like Hyman Rickover was a four star admiral for 30 years that is something we can't even contemplate today we almost view our officers as cogs to keep moving around. Every two to three years, you have to keep moving.
- 52:24
As the first director of the nuclear Navy, of naval reactors, you know, he was in that role for a very long time. But that role, even today, is an eight-year stint, which shows you the primacy of people, that we understand with something this exquisite, something where this much knowledge and continuity matters, you don't just keep pulling people out every two or three years. And our ships, our subs, are the safest in the world by a long shot.

So every six months, the Soviet submariners would get six months of respite at Sochi to recover their white blood cell count because they were getting irradiated. We've had no deaths due to irradiation. You know, he built it with the specification, this has to be safe enough for my son. He built it to a specification that is 100 times safer than the minimum safety standard. And that is the sort of aspiration only a founder could have.

Yeah. This is going to be a great movie.
