None of those systems are autonomous, people still handle the decision-making. Also, AI does not mean faster or more advanced compute; the fact that it requires so many cycles and watts is a testament to its relative inefficiency.

Aerospace code is much too thoroughly-vetted to use something as slow and imprecise as a modern AI system. Existing realtime platforms and sensors are plenty fast, and you can prove that they'll work correctly. Plus, when you're procuring chips to run in an adverse environment, advanced process nodes will probably be too fragile and prone to interference.
