I feel like the proposal also glosses over why a merger is necessary and desirable to accomplish the goals.

Why couldn't xAI just, you know, contract with SpaceX to launch its future Datacenters In Space?

Wouldn't a company focused on a single mission, Datacenters In Space, be better at seeing that goal to fruition, instead of a Space Launch Company with a submission of Datacenters In Space, which might decide to drop the project in three years to focus on their core mission of being a Space Launch Company?

Even granting the goal as desirable and possible, why is a merger the best way to pull it off?
