By "spacefaring" I mean the ability to live in/utilize space (asteroid mines, fast travel like lightspeed, harnessing greater energy sources, terraforming planets, etc.)

Edited by Trash Bags: 4/20/2016 3:34:40 AMYou forgot the (No: we will self destruct via stupidity) option. I would love to see it happen but I don't expect humanity to last another two hundred years. Too many variables. Political correctness, 4/20, Muslims are all contributing factors to our demise. Political correctness is self explanatory as to why its dangerous. Non-medical pot smokers or those 4/20 people are some of the biggest idiots in the world. Instead of worrying about more important things, they worry about their next smoke session. Muslims are the most violent group of people in the world and as you can see, killing all non-muslims. And as you can see, the video above proves modern muslim stupidity.
