The Mars obsession absolutely blows me away. Like, he's obviously read KSR's Red Mars. He's obviously aware of the conditions out there. Mars is a fuckin' bummer. It is absolutely hostile to human life. Sure, we'll land people there, and maybe set up some sort of station if we really want to throw a few trillion dollars away from actual problems here on earth... but it's not going to be pleasant. Not anytime, ever. The gravity sucks. The dust and fines suck. The storms suck. And last for months. The temperatures suck. There's no "outside". There's no trivial way to generate power at scale. There's no magnetosphere, so you'll get cancer. The soil is poisonous.
Elon's stuck with this 12-year-old-boy absurdity about "becoming interplanetary to save the species" as if Mars could ever be a practical lifeboat when we inevitably drive the planet into the ground or a meteor hits. It's... absurd, puerile fantasy.
The funniest part is that the Mars Trilogy is hella optimistic about the tech needed to get and live there.
Let's say, you simulate a long museum hallway with some vases in it. Who holds what? The basic game engine has the geometry, but once the player pushes it and moves it, it needs to inform the engine it did, and then to draw the next frame, read from the engine first, update the position in the video feed, then again feed it back to the engine.
What happens if the state diverges. Who wins? If the AI wins then...why have the engine at all?
It is possible but then who controls physics. The engine? or the AI? The AI could have a different understanding of the details of the base. What happens if the vase has water inside? who simulates that? what happens if the AI decides to break the vase? who simulates the AI.
I don't doubt that some sort of scratchpad to keep track of stuff in game would be useful, but I suspect the researchers are expecting the AI to keep track of everything in its own "head" cause that's the most flexible solution.
