We are the chronically online humans. Before we existed we had to learn to interact with people that mapped realities in different ways, we had to learn to accept, empathize and yes, even tolerate other perceptions of truth.

We the chronically online decided that the effort was too much, too costly, the dopamine hit from confirmation bias is too tempting. So, we created communities filled with people that mapped their reality in the same way, or at least similarly as to not have to practice empathy or tolerance.

We the chronically online then reverted to tribalistic behaviors, not only other, something we've done for ever, but also going on the offense, as if we were fighting for a resource, for food, when In reality we fight only for our egos.

How do we fix it? Don't know, and I suspect there is no way to do so at this point.
