None whatsoever, other than what info is available via open source, nor do I claim any particular expertise, what's your's?. Instead of cherry picking one sentence out of context which suits your stance, why not try answering the actual question I posed in the comment you quoted from?
So no particular expertise, and no cherry picking, your ‘question' isn’t really a question, you seemingly admit the ac is way ahead of whatever else is out there then pose alternatives that don’t even exist, and possible problems.
will it still provide that edge over updated and in development systems? Will the updating of the onboard sensors/avionics be enough to counter the ever evolving IADS threat, or will the basic airframe and LO technologies built into it be the ultimate limiting factor?
Since no other country is producing anything of that standard, or numbers of F-35’s already in service, then it would seem that a qualitative edge over potential opponents already exists.
‘But’... one may be sure that you will find disagreement with that.
