The problem I have with the article is that it doesn't actually ever talk about if the ideas are good or not. It points out that the MVP of the ideas need a lot of work, and talks at length of why they don't work. For example, he spends a lot of time talking about how maintenance on the F35 isn't the same as the F18, so people who maintain the engines will have to change how they work, and new types of people will have to be added. Most interesting part of the article for me was learning about passive detecting. https://en.wikipedia.org/wiki/VERA_passive_sensor
Interesting, though i believe the doctrine is that stealth aircrafts rely on a data link from a AWACS to guild them to the target, and only turn on their own radar when within weapon range, then only for as long as is required to confirm target and launch the missile (who invariably has its own radar these days).
Not to say that there are a myriad of assumptions that go into making an stealth aircraft, as was demonstrated when apparently an F-117 was downed by a modified SAM site.
