Ok. So essentially Terafab is not a plan for a 'standard' semiconductor fab, but includes mask production, test house and packaging under one roof. This alone is a very alien concept. If they only achieve this alone, not even considering reaching the crazy output numbers, they're

Given that several companies make advanced chips, but no companies have ever made fully reusable rockets or achieved SpaceX scale, I think Starship is harder, but we shall see.
Terafab will technically be two fabs, each making only one chip design. This greatly simplifies process flow and allows more linear, adjacent movement of the FOUP.
A super high production rate allows us to test very quickly what steps can be deleted, simplified or sped up, even after the design is fixed. Current fabs are extremely conservative, operating on rigid historical heuristics, which are mostly, but not all, correct.
Anything that is a rate limiter at the machine level means that machine will be redesigned, unless already at limit of physics.
Having new iterations of a chip design be produced every day in the research fab (with <7 day lag) means being able to try out many high risk, high return ideas.
Etc
In any event, there is no other way to reach extreme scale, so either we make Terafab or we will be stuck at the ~20% chip/memory output growth per year of the current industry.

Happy Birthday Giga Berlin!
4 years ago, we started production with delivering the first 30 cars to our customers! Since then, it has been a unique success story:
- produced and delivered more than 700.000 Model Y 💪🏼
- created nearly 11.000 jobs 👷♂️👩🔧
So much more to come!

Whenever space data centers become cost effective, they'll get there first for the company that is vertically integrated with the software, the computer hardware and the launch capabilities.
Terafab is news, but it's not a surprise to anyone that's been paying attention.

This is still only the beginning.
