Say we have a person living on his property, and his house is half a mile from your nearest Windstream connection. If you run fiber to him, he's going to be the only one on that service. Windstream will actually spend that money to run the line for free? That is amazing.

The only time I've seen free runs is when a bunch of unserved households together ask for the service, so that the ISP knows it'll get a greater income for that expense.

I have lots of tall trees around me, but the clearing around the house allows plenty of line of sight to the sky. If the trees were closer I’d put it on the house.

This isn’t like traditional satellite. You can have multiple satellites in view and it’ll pick the best one.

A while back I calculated out how much it would cost to fuel Starship based on existing known numbers. I can't remember exactly, but it was only like a few million dollars, and that to send 100 tons to LEO. Musk's goal of $10/kg to LEO seems pretty doable.

Everybody in the world is fighting over battery supply to ramp up EV production, and Tesla is making sure they don't have to fight like the rest. It's a good long-term strategy. Even if their sales went below their battery production in the future, then they just become a battery supplier for the others.

The days of it being okay to blow stuff up are now over for Starship. A full stack blow up would damage that very expensive launch tower, so they now have to tread carefully.

I doubt it. Bezos built BO as a standard rocket company with standard development procedures -- money heavy but hardware poor. Do all the design up front, make it perfect, so you know nearly 100% that it will work. This did make it easy for him to hire some of the best in the business, but it's also a very slow and restricted development method. There's nothing to learn from in this process, only putting your ideas to paper, and eventually into hardware.

Musk drew from his software development days and made it hardware rich. Build, test, evaluate, wash, rinse repeat. See what works in real life, see what doesn't, and change accordingly. This is why we saw so many rapid unscheduled disassemblies. But it's also why SpaceX advanced so quickly.

Last year they started doubling down on AI training, so that by the end of the year they started installing a custom-designed AI training supercomputer that does 1.1 exaflops in only ten cabinets. For reference, the current fastest supercomputer in the world is 1.6 exaflops with with 74 cabinets. Technically their supercomputer does this at only 16 bit floating point compared to higher precision for the other computer, but it doesn't need more than 16 to train AI.

They also have an advantage in batteries in that they make their own, and they're ramping up mass production of a new battery design that has much higher density. They're not just buying exploding batteries from LG like GM is.

Also, nobody else has a Class 8 truck with decent range.

BTW, the tallest, heaviest, and most powerful rocket in history just passed its full-stack fueling test. Yeah, just playing spaceships.
