The classic dogfight can only persist in the hearts and minds of old pilots. A modern state of the art unpiloted fighter, with no human pilot or the burden of life support, and G limitations will be lighter with the same engines, capable of 30-50+ G maneuvers(for which is has been specially designed), with modern long range standoff weapons and suitable radars, will slaughter any human if faces. The high G ability will leave any standoff missiles fired against it in the dust by active evasion. It will be vulnerable to high grade stealthed missiles. as well as hard ballistic stealthed rounds shot from afar - unless it detects and evades. In fact, any modern robot craft will perform high G random jinks to make path prediction difficult. The soone the USA realizes this, the better. You can be sure Russia/China have learned this lesson.
