> running identical software on multiple computer systems is the name of the software-architecture game

In the railway signalling industry (which for historically obvious reasons is obsessed with reliability) there even is a pattern of running different software implementing the same specification, written by different team, running on a different RTOS and different CPU architecture.

This is also true of the space shuttle. The failover '5th' processor was running an implementation done by a completely different sandboxed team to hedge against institutional or systemic errors not caught by the first team. So much thought put into these systems.

This, in the context of 'modern vehicle safety standards' still makes me cringe when considering the "safety" put into modern autonomous vehicle systems.
