A person from a decade or two ago might find a lot of things odd such as taking selfies, Facebook checkins, talking on a bluetooth headset, holding a 5.5" phone to your ear when the 90s was all about miniaturisation, the shake-to-shuffle a song, etc.
It's only an oddity because it's not common.
I am sure that things will gravitate toward gestures as this space evolves. It just seems like a very convenient way to interface and offers the path of least resistance for users.
