I'm in that group.

It's not "getting used to", I feel like that gesture is less practical. It involves or using the "circle" to assist on how to use the gesture (creating a black void on the screen that you need to plan your use of the phone around) or having the swipe that 1) is not as reliable in my opinion and 2) can be triggered accidentally

For me is like claiming that touch screens on cars are the future and people are too old to get used to it.
