given that humans took less than 100 years to get powered flight, less than 50 yrs to get rocketry, i expect interplanetary colonization to not be in the too distant future...

I mean isnt the main question if we destroy ourselves before that time?

I'ma have to see a viable colony on Earth's moon before I'ma able to even consider the possibility we have a snowball's chance in Hell of surviving someplace like Mars. Problem is… Can humanity survive itself long enough to even get a colony on the Moon?
