IMO we have had decades of iterative change and exploration, but no major shifts or innovations. Like there have been many takes on the sounds of a guitar, but when do we get to the age of distortion piano-ish thing but entirely different? It seems like most major cultural shifts come from the cauldron or crucible of hard times. We may be near such a nightmare, so what do our kids create from the ashes?
One thing I’ve seen as a new hotness in high art is that the themed experience is crossing the threshold from low art to high art. What would have been considered a theme park ride is now bring presented as an interactive experience worthy of being in a museum. Of course, you will have to exit through the gift shop.
