I actually brought this up a long time ago, in a roundabout way.

Short Version: Human agency has been increasing since we first picked up a rock and used it to open a stubborn coconut. As human agency increases, the potential violence that an individual can perpetrate by themselves goes up. There will come a time where large sections of the human race will have the ability to destroy almost everybody, and will have to consciously choose NOT to do that. If we do not develop our moral sense fast enough we are going to hit The Great Filter and that will be the end of our story.

fallingsaucer are you still out there somewhere?

You can also use this as the starting point for comparing political leaders, as a thought experiment loosely termed 'Perfect Weapons.' It goes something like this.

We have come into the possession of perfect weapons. With the push of a button, a person dies without any mess or collateral damage. We can use these weapons on the battlefield, as assassination tools, threats, etc. Now, imagine giving control of this weapon to someone, who would they kill?

Barack Obama would have one list of people he thinks should be killed.

King Salman of Saudi Arabia would have a different list. Ibrahim Awad (Abu Bakr Al-Bagdhadi) would have a different list. Theresa May would have her own. Etc ad infinitum.

The comparison of these lists would be very interesting.
