No, I think new developers who are "native" to this world will be a whole different breed. Maybe still not as good as seniors (as has always been the case) but closer than ever.

I could certainly see a wave of oversupply of juniors followed by a wave of undersupply. Say we stop hiring many juniors - a lot of people trying to get into industry right now are in for a rude time. Then maybe fewer people trying to learn it over the next few years, but those who do end up quite valuable.
