There was a point made recently by Musk that the whole clean room idea is outdated if you can just ensure the path the silicon takes from wafer to lidding is clean.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.
