Yes, it seems like the younger generation is conditioned to a different form of UI "discoverability" than those of us who learned computing in the desktop era. I look for visual indicators, even on touch user interfaces, so I am always missing functionality that is hidden behind a non-visual interaction. "Pull down to refresh" is something I would have probably never found in many applications if it had not been pointed out to me. iOS is especially notorious for hiding features behind odd/innovative UI behaviors such as press-extra-hard or shake.
I almost feel as if "just show me visual indicators of all functionality because I am old-fashioned" needs to be a new accessibility concept or setting.
