Whilst I would agree it looks like we're heading towards an era where traditional pilotted jets may be obsolete, there are several factors for why the Russia-Ukraine war might not be so representative.
Firstly, because the Soviets predicted they would lose the air war in a NATO-Soviet confrontation, Soviet air doctrine was based around air operations in their own territory or close to the frontline to reduce plane vulnerabiility. As a post Soviet state, Russia has continued this trend. Therefore, you might not expect Russia to try to the same sort of air domination that the USA would. Secondly, yes, AA: as a post-Soviet state with the legacy of Soviet doctrine, Ukraine is also centred around generous ground-based anti-air capability that makes it perilous to try extensive air operations. Thirdly, the Russians are still using Soviet-era technology: even though they will have upgrades since the 1980s, their jets must still be considered relatively vulnerable to anti-air capability.
No country is going to use its latest technology unless it has to: the risk of losing a plane where enemies can get at it - and giving away a lot of secret information on its capabilities - is too high. They want to protect the knowledge for as long as possible. The Russians won't be using their latest jet over Ukraine, and the USA won't be using its over enemy terrain for years unless it's a really major conflict.
