What will the next age of innovative art culture create?

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?
