But people still capture things in the sky if there's something to see. Plenty of footage exists of low flying aircraft and meteors, for instance. People aren't looking down at their smartphones all the time, completely blind to the peripheral universe around them. And there are also dashcams, security cameras, etc, to consider.
In what way does it seem like that? There are many, many more _sightings_ in the current decade than the last, with a repeating pattern for about 50 to 70 years or so. Cellphone cameras are partially responsible for that, but unfortunately camera quality of most phones kinda sucks. That represents a different set of problems.
