I am with the commenter who pasted a link to https://xkcd.com/1235/

With almost every one carrying smartphones we should be seeing a lot more high resolution videos of these objects. Especially we would be having recordings the same event from different angles.

Now I am not saying there are not a good amount of UFOs there, there are, but that still doesn't mean they are aliens. They are just unidentified, and maybe some are not even objects but illusions, or optical effects, or natural phenomena.

The majority of mobile phones don’t have a telephoto lens good enough to take a useful picture of something ordinary sized high up in the sky. Just ask anyone that’s tried to take a decent picture of the Moon! Samsung famously inserts a picture of the Moon into photos to avoid user disappointment.

I do agree with you, by now I would have expected a lot more footage if UFOs were really visiting us. However that amount — if they were here — would still be a lot less than you might expect!

This is a well meaning take but it’s not a good scientific argument. It’s correlation, but doesn’t say which way the arrow of causation is pointing.

Suppose the phenomenon being observed is cloaking tech. By definition, it’s something that is forever on the edge of what photon-based digital recording devices can observe, remaining consistently “blurry” despite massive increase in quantity and quality of recording devices.
