Thanks, the insights about Super Heavy vs Starship are interesting.

About how "huge" it is, I understand that it is economically huge: Musk will get even richer.

I would be interested in knowing how "huge" it is in terms of engineering. Like, my understanding is that they needed to invent new maths to go to the moon in the 60s. Does SpaceX compare with that, or is it "just" what you can do with a lot of money and powerful computers?

Genuinely interested, even though rocket fans will hate me for not knowing the answer and daring asking. Bring the downvotes!
