It'd be really awesome if microprocessors, even at a low-end process node like 130 nm, could be made with room-sized machines or smaller. There's a lot of space for companies wanted to manufacture their own MCUs, for instance, without relying on massive supply chains.<p>I think this'll happen at some point, as silicon manufacturing hits final roadblocks and becomes increasingly commoditized, but it'd be nice if it were sooner rather than later.<p>(This would be nice for self-sufficient decentralized communities being able to produce their own microelectronics as well.)
