I don't think the vibe shift they're describing has fully taken place yet, but I think the foundations have been laid and it's started. It's probably going to be a while and take further societal changes to fully come into fruition, though.
AR glasses coupled with a sophisticated input device (fingertap? tounguetap?) will eventually be able to fully replace a touchscreen interface. And from then on it'll eventually become dated and rude to resort to pulling out touch screens during a social event.
Mind you, inconsiderate people will be as distracted as ever, and will continue to halfheartedly pretend they're listening to those around them. They'll just need to find a new method to achieve maximal obnoxiousness.
