I'm agreeing with Corey and Braixen. I don't think it's making us more lonely, per se, but making us feel less inclined to go outside.

To ask if it's making humanity lonely as a whole is a bit of a hasty generalization. As Tenacity said, our personality and how we view the world makes a big difference on if we feel lonely or not.

Everyone also defines "lonely" in their own way, further supporting the notion that this is something that occurs more on a case-by-case basis.

But I totally agree that for quite a few of us, it makes us feel less motivated to go OUT and go DO things.
