You have a lot of solid points, but note that Linux is currently being used by SpaceX in an even more safety-critical aerospace setting.

Also note that interpreters have their place in safety-critical aerospace as well: some satellites run Forth.

I disagree with the 'more' - how many lives are at risk with a SpaceX failure vs. a self-driving car failure? This is even without multiplying by number of users.
