Autonomous driving is still nowhere near 100%, so why suddenly jump to fighter jets? Is this more of Hegseth's foolhardy bluster and injected testosterone? The tech isn't ready. They should start with golf-karts, not fighter planes.

Edit: Okay gang. If aircraft are easier to fly than cars are to drive, where are all your pilot licenses? If you've faced rush hour traffic, flying a military jet should be a breeze! Please, go volunteer your neighbourhoods to be the first for AI jets to be tested over. We can put a mock enemy target in an empty lot and watch them pick it off, first try, with zero collateral damage. Easy peasy!
Fighter jets don't need 100%. In a war, we accept a much higher rate of casualties than we do in day to day driving. I would also imagine that while planes are harder for a person to pilot, they are easier for a computer. Most of what makes them hard is mechanical, not dealing with unexpected situations.
I reject the notion that planes are harder to automate.
There are many ways that flying is an easier solve than driving, believe it or not.
Planes might be easier, large empty space in the sky
