I'm convinced this was a psyop actually, with the intent of delaying other country's 5th gen programs or development of quantum radars. It definitely had some cost overruns but I think its performance as a fighter is pretty impressive.

Criticism is fair however: they did probably extend themselves too far with the helmet technology, and I do have concerns about touch screens in cockpits (a touch screen requires you to take your eyes off of a target to move your hand to the right location, rather than locating a button by touch).
