I don't think it is "out there" really. It's pretty simple. Bombs, plate, boom. It went through a pretty thorough development cycle at General Atomics, and they didn't have modern simulators. I think it would be great if we get a moon base going that could build it from regolith. Then you ship up the bombs in a few runs of Starship and you have a badass solar system exploration rig. From the docs, they could get to Saturn in something crazy like 1 month.
