One goal of transhumanism is breaking confinement to Planet Earth, and a few things stand in the way:
Our immediate neighbourhood is mostly uninhabitable: Venus, Mars, and the Moon are not viable options
for settlements.
Even much of the Solar System is uninhabitable; Ganymede, Callisto, Europa, Titan, Triton are currently
uninhabitable.
We are not certain if we have inhabitable planets within 3 parsecs, and even this small radius is beyond
our reach.
Technological breakthroughs are even more problematic.
Besides these obvious obstacles, what have been keeping us confined to Planet Earth?
