They can’t.
Operating a FAB requires employing PhDs that are willing to work 8 hours shifts with no breaks (each removal of a bunnysuit is an expensive exercise), and there’s no reason to believe SpaceX is capable of hiring such people.
There was a point made recently by Musk that the whole clean room idea is outdated if you can just ensure the path the silicon takes from wafer to lidding is clean. Seems solvable to me, but leaves me wondering why it hasn’t been done before. I assume there is no human handling of raw/etched silicon now anyway, so why does the whole room need to be clean?
The semiconductor fab process changes dynamically to manage yield. It is not a static environment, automating with robotics is fine when things are static like a automotive assembly line, but high end semiconductor fabs are a different beast (The analogy I heard was repairing a plane while in flight). Robots are not purely clean as well they shed contaminates as well, which must be managed too. Entropy is the reason why we still need humans in the loop.
hmm yeah. its cool that musk knows more about this than the entire industry
It wouldn’t be the first time an industry got bogged down by prior knowledge. Hell, it happens to all of us.
You could probably apply that logic to any innovation in any industry no?
Reusable rockets likely got the same ridicule, as did fast satellite internet, self driving and fully electric vehicles.
I can understand that Musk does not have the most palatable personality, but floating ideas and at least attempting innovation regardless of outcome over a long time is a net positive for society and should not be discouraged.

So what? Maybe a hand full of full bunnies per shift, and another dozen or two half-bunnies. There aren't more. This can be seen/validated by some older yt-videos, where something went wrong in the fab, for instance a https://en.wikipedia.org/wiki/FOUP ejecting a wafer in wrong ways into a machine, then being ejected by that onto the floor, and shattering. Causing all systems to stop, and all the warning lights beginning to blink in an expanding cascade. At about 4:30AM. Maybe 20 seconds later two half bunnies with face masks appear, another 10 seconds later a full bunnie. Some gesticulating ensues, full bunnie opens his suit, gets his flip phone, half bunnies downing their masks. All looking very concerned and exasperated. Having a really bad day. No more bunnies appear over several minutes. Video ends.
