I will say it one more time
Failr or succeed, people will try to head off to the stars to start
life anew and live the way they want to.
And I am sure a few will make it despite all the doom and gloom
warnings.
That's the thing about humans - they have many flaws but when
they get determined enough, not even the Universe will stop them.
And sure as heck not a bunch of cranky people on the Internet. :^)
