By the way safety critical ethernet already exists and is already in use in planes for instance. Reducing the number of wires doesn't require reducing the number of microcontrollers, those are two different problems with several orders of magnitude difference in complexity.

Older planes still use ARINC 429 protocol which is one way serial link where one source can talk to multiple clients. But since it is used only in aviation, the boards are really expensive. It is cheaper just to use Ethernet and require special verified routers where software is formally verified.
