Note that the original article doesn't say anywhere that F-35-like capability is not needed.
You're confusing short range, highly Ukraine-specific Group 1 quads with long range OWA drones.
Ukraine is a real war and it is about men and women crawling in the mud constantly terrified of getting blown up. It is literally battle of the Somme again. How do you recruit college kids for that?
Re. no swarms of drones because the factories have been bombed, do people really think that'll work on China?
RU/UA is special because RU completely screwed up the first 3 weeks of the war (likely because of the culture of sycophancy Putin has, similar to Trump) and was driven out of central UA. Russia is too proud to admit they lost and UA wasn’t allowed to attack into RU territory until their suppliers (US, EU) were confident RU wouldn’t nuke us in retaliation. Now UA is busy dismantling RU’s economy and war making industry. Ultimately it’s not comparable to any other war of our lifetimes for several reasons.
UA drone factories aren’t in large industrial buildings. They have hundreds of office / home locations where the parts are printed / assembled. RU largely has a very few mega military vendors who make drones / missiles and they have consolidated their efforts in a few (now vulnerable) locations.
F35 capability is excellent for preparing the battlefield, such as the first few hours when softening up air defenses.
But don’t underestimate how much all countries are learning from watching RU/UA or US/Iran. Drones will continue to evolve to meet the gaps in affordable interception, affordable anti-5thGen aircraft, etc. UA now has armed land, sea, and air drones and each has variants like scout, bomber, interceptor, etc. we will continue to see specialization and comparative advantage evolve in the space.
Just for your benefit, stealth coatings and materials (not "paint") are a tertiary defence after shaping and electronic warfare.
Group 3 UAS can't be assembled in homes and office buildings in any meaningful numbers. They are too big. Even Group 2 is marginal. I think you're confusing Group 1 quadcopters with long range OWA drones like Shaheds.
This shouldn't be a big surprise to Russia or anyone else, as it has precedent. German aircraft production peaked in 1944 at the height of allied strategic bombing.
