"Modern" jet fighters, yes. I believe it started to be "hard" to fly manually with the F-16 and now it is completely impossible, but feel free to correct me.
F-16 was the first inherently unstable jet fighter, and the first one that featured a full fly-by-wire system with no backup. If you want a jet that is completely impossible to fly without a computer, F-16 is already one of them - there is nothing special with the F-35 about that.
Only on HN do people argue about an initial comment that they find nothing incorrect about, until they can find a little thing to be able to write "ahah you're wrong!"
I didn’t think you were wrong, just providing context for non-aviation people.
