It was an interesting read and how he thought the canard made it like an F-16 at supersonic speeds, which I could see as being true in that the canard shifted the AC forward at super sonic speeds to limit supersonic trim drag. Whereas, the F-16 being unstable at subsonic speeds allowed the F-16 to be slightly stable at supersonic speeds, thereby limiting it's supersonic trim drag. However, I would argue that the F-16 took it a step further with it's subsonic maneuverability due to being unstable at subsonic speeds.
Although, I think it's safe to argue the entire MiG-21 program could be seen as the godfather of the LWF program.
The MiG-21 already outperformed the F-4 at slow speeds handily, the Ye-8 would have improved somewhat subsonically due to the higher thrust/weight ratio, while also doubling allowable G at high speed and high altitude, This would probably be enough to ensure superiority over the F-4 at all speeds and altitudes and it would have reigned supreme until the F-15 / F-16.
The USSR went totally the opposite way with the eventual MiG-23, .....
