I think he will spin Tesla off since electrification and autonomy are no longer cool (he can’t build good quality cars or reliable FSD)

FSD is incredibly reliable. Build quality of US built cars is middle of the pack, Europe/China built Teslas are top of the pack.

Oh c'mon now. Damn model 3 and model S I have driven were considerably lower quality interiors than an ass end Citroen or Fiat. The Model S, a 2023 model the doors didn't even fit properly. And that was all Europe.

As for FSD, nope. Unless you redefine the word reliable.

Edit: I owned a 2018 Model S as well. Literally the worst fucking car I have ever owned or driven.

In fairness, solar cells can be about 5x more efficient in space (irradiance, uptime).

Solar cells have exactly the same power rating on earth as in space surely? What would change is their capacity factor and so energy generation.

Atmospheric derating brings insolation from about 1.367KW/m2 to about 1.0.

And then there’s that pesky night time and those annoying seasons.

It’s still not even remotely reasonable, but it’s definitely much higher in space.

We just had an X8.1 CME event, I just want to point out that at any moment we could have an x40 (we had a carrington event already in 1859) or higher event and all those sats at low earth orbit would be fried and start hitting each other, if SpaceX keeps launching more it becomes incredible probable that we might hit the Kessler Syndrome, and we would legit lose access to Space for a WHILE, including all of what satellites entail.

Are we ready for that as a modern society or are we going to start enacting regulation against it? I'm sorry but people wanting internet everywhere does not justify we going back to the dark ages for a decade or more.

From the Big Short (movie)

Jared Vennett (narration): "In the years that followed, hundreds of bankers and rating agency's executives went to jail. The SEC was completely overhauled, and Congress had no choice but to break up the big banks and regulate the mortgage and derivatives industries."

"Just kidding. Banks took the money the American people gave them, and they used it to pay themselves huge bonuses, and lobby the Congress to kill big reform. And then they blamed immigrants and poor people, and this time even teachers."

Yeah, that's the point ... it's stupid to believe humanity is capable of deploying that much infrastructure. We cannot do even 0.01% of it.

You operate them like Microsoft's submerged data center project: you don't do maintenance, whatever fails fails. You start with enough redundancy in critical components like power and networking and accept that compute resources will slowly decrease as nodes fail No operational needs is obviously ... simplified. You still need to manage downlink capacity, station keeping, collision avoidance, etc. But for a large con…

How many submerged datacenters is Microsoft operating?

None, https://www.datacenterdynamics.com/en/news/microsoft-confirm...
