If their vision comes true, the Air Force would enter the 2030s as a smaller but more flexible force that is better positioned to win America’s wars, with sharper leaders and savvier airmen.
I would point out that quantity has a quality all its own. The English found out at Islandwana against the Zulu, the Germans with the Me262, the Tiger II and the vengeance weapons (V1-V2), and Afghanistan vs anyone, ever. Those are some of many instances where a technologically inferior force prevailed, often by sheer numbers or better tactics.
The idea that only a small number of technologically superior weapons will prevail is dangerous, as in the Bismarck and Tirpitz or the Yamoto and Musashi the former ultimately defeated by a 'stringbag' torpedo plane. (The bombs that hit Hiroshima and Nagasaki are an argument otherwise.)
Yes, having the latest 'gee whiz!' weapons is great, but that also means developing the tactics to utilize them to best advantage, and having enough of them to defeat the mobs of lower tier weapons they will face. Reliability is an inevitable factor. Next gen that doesn't work will be beaten by the stuff that does.
