But Who are We?
The fate of question marks on this planet is unclear.
Can we preserve the question mark through the colonization of other worlds? Is this even an appropriate way to do that? (morality vs. economics again).
What about Colonization of Space ?
Why would we colonize other worlds?:
Best case assumes 1.7 7.8 billion in 2050 declining to 4.3 billion by 2150
Current fertility rate is 3.3. Fertility rate in 1970 was 4.5
The above calculations, however, do not adequately factor in increases in global life expectancy.
The above reasons would all exist if your species is unable to engage in multi-generational thinking and planning. Colonization requires this.
To move several (hundred) thousand individuals off this planet towards another world is a serious effort and a serious use of planetary resources.
Such large scale colonization requires a 50-200 year planning and implementation effort. Our technological culture has repeatedly demonstrated an inability to do this kind of long range planning.
This might be a form of self-censoring. Non-equilibrium cultures can't colonize because, when they feel the need, it will be too late (resources will be gone).
Why would equilibrium cultures colonize then when they would have no reason to?
