I know this was rhetorical but the obvious answer is a complete lack of any actual ideas. “Just automate it” is a common refrain from people who don’t know how to fix the actual issues with any domain.
Remember how we installed traffic lights all over the roads and now car crashes never happen any more at intersections? Truly automation solves all problems.
It sounds like you're not asking anything at all
Just to play it out a bit, are you imagining that a pilot would be reporting a mechanical failure upon descent into busy airspace to some type of like AI voice agent, who will then orchestrate other aircraft out of the way (and not into each other) while also coaching the crippled aircraft out of the sky?
Are you imagining some vast simplification that obviates the need for such capability? Because that doesn't seem simple at all to me.

The concrete reason your ideas won’t work is you don’t have any.
