We now have the technology to destroy the planet on which we live, but have not yet developed the ability to escape it. Perhaps in a few hundred years, we will have established human colonies amid the stars, but right now we only have one planet, and we need to work together to protect it.
To do that, we need to break down, not build up, barriers within and between nations.
I’ve recently been discussing the idea of a basic income for all human beings with a skeptical friend. I tell him that just because something hasn’t worked (or been tried) before doesn’t mean it can’t work. That’s how new ideas and paradigm shifts happen.
