Ok I agree with that, maybe I was not being clear enough, I meant stealth as it is now.
I'm sure new forms and technologies of Stealth will appear in the future ,as will new and more effective ways of detecting threats.
The technical race in weaponry is a fact , now more than ever but that is no reason to give up on the basic principles of weapon tech design, in case of fighter-jets, performance , numbers (affordability), maintainability matter just as much as it did in the 40's or 50's.
As an analogy look at other segments in the military, look at it's most basic component , the soldier, just like 200 years ago you need a well trained, physically and mentality fit soldier to begin with, everything extra you can expand upon only if the basics are ok.
Same goes for hand-weapons, ships, rolling equipment, etc... .
The F35 doesn't deliver on some of the basics (for the right price) and is therefore compromised from the very beginning.
