Perhaps you're right about the future. Photonics based radars in the coming decades certainly will make current LO technology obsolete. But the fact that many airforces around the world including China's are investing heavily in stealth, goes to show that it is extremely valuable and effective today and in the near future. It will be at least a decade before aerial warfare is again revolutionised by new missiles, sensors, jammers, drones, and AI. For now, if stealth is truly as obsolete as you suggest, why would Russia, India, USA + JSF countries, be pursuing stealth? Not to mention, Korea wants to start its own program with a few partners. Their LO fighters will be at least a decade away from LRIP.
the reality is stealth is too expensive, specially when this has TVC nozzles, Supercruise and advanced avionics.
Just consider 20 F-22 will spend in one hour a million two hundred thousand american dollars in just a single flight hour each one.
So this limits the number of flight hours besides they break all the time and need maintenance.
F-16s, Su-27s or J-10 are not going to be phased out and being retired any time soon.
Add that you can detect stealth aircraft, people have this fantasy they can not be
detected, but very likely by airborne means they can be detected in ranges of 120-180 km.
true, it is harder and much more expensive, but possible! these aircraft are a lot propaganda.
I can assure that aircraft like F-16 and drones will fly more hours, have better maintenance and practically have not much different losses than F-22s in big war, by big war i mean superpower versus superpower.
Is good to have stealth? yes of course, it forces the enemy to revamp and upgrade all the air defense network, thus it creates economic losses and in times of economic crisis social unrest.
Plus versus small nations with a few of obsolete aircraft are effective but more by sheer numbers and electronic jamming.
As economic items allow the industrial military complex more money and internal prestige in the propaganda war for both internal and external purposes.
If you do not believe it, in 1999, Serbia shot down a F-117 with an obsolete SAM, and the F-117 was escorted by F-15s and one time almost one MiG-29 shoot down a F-117 but it was prevented by the escorting F-15.
