I don't think that Linux can be "realtime enough" for safety-critical functions.

But I expect that it can work just fine for interacting with those systems and monitoring, configuring, and logging them and communicating state between them.

Sort of like how you will pull your hand away from a hot stove before you become aware that you are burning it. But then once I am aware of it I can take further steps to deal with the damage.. like turning off the stove, treating the hand, etc.

Bit late to the table, Linux is already used in safety critical systems and has been for years. This LWN article [1] gives a good overview of the various approaches and some of their tradeoffs. I can provide talks from groups within major automakers talking about their own usage too, if you'd prefer.

But Linux is fine given all the caveats, limitations, and system designs are done properly. This is where most systems are headed.
