Yeh, I guess you really did miss something. I’m sure the purpose of mining a solar system was not to make more simple probes.

there was some stuff about his drones destroying entire solar systems for raw minerals, that just seemed plain nonsensical to me?

Not sure what exactly seems nonsensical to you but it’s a well known concept that is also explained thoroughly in the books. You might want to read up on von Neumann probes.

That’s the thing though. I bet you Valve is already prototyping an ARM based Steam Deck. It’s the logical next step to improve performance and thermals/battery at the same time.
