We're not mere animals. Well, at least
some of us aren't.
We have the ability to choose and overcome our basic nature. We can both hope and strive to do better. We have the ability to overcome these petty "me first" impulses, little by little.
I'm not naive. It won't happen overnight, it'll take a lot of work and even fighting and/or killing if necessary.
But the dream where we ALL win begins with us saying that we CAN. And then we need follow-through, determination and sheer will to make it work.
The greatest example of this in my mind is when thankfully in the 1860's there was a President that put his life where his mouth was regarding this very concept. Several followed, and all paid with their lives. But for a few years since, it seemed we were moving in the right direction.
Sadly, the US went the other way in 2016.
We can have the future Steve Roddenberry presented in Star Trek. We already have tricorders!
Seriously, I believe the recent communications revolution and leaps forward in technology will make this possible now more than ever before.
