I wonder if these classic patterns still hold now that everyone competent has read these 1990s era books.

I could be strongly biasing myself without realizing it but I think they've become less common except on really grand scales where no single industry player is big enough to really control things

Here's a few I see:

podcasts and YouTube are successfully attacking conventional television and radio

Home recording studio equipment improvements have seriously been eating into studio time.

Home audio improvements have made the high end less relevant

Display technology improvements have made affordable displays eat into the high end market.

I think transportation and energy are the next big ones; solar panels will be so cheap that they'll start to be integrated just about everywhere and smaller electric cars (under 1500lbs or so) will become so affordable that those who drive for pure function will start adopting them en masse

The Innovator Dilemma doesn't mean you can't do anything about it. Its just harder to do and you need to make the necessary investments (usually doesn't even require that much money) and need to have the right strategy to do it.
