23. Erroneous conception that global risks threaten people only while we are Earthbound, and resettlement in space will automatically solve the problem
The scale of weapons and energies which can be created by people on the Earth grows faster than the rate of space expansion. Meaning, by the time we can expand into space, we will have created threats which can self-replicate and intelligently target human beings, namely advanced Artificial Intelligence and autonomous self-replicating nanotechnology. Information contamination, such as viruses or a computer attack, would also spread at close to the speed of light. Space is not a panacea.
