Should we colonize space to mitigate existential risk?

Sounds good in theory, but we don't have the expertise to do that. If we did, trips to Mars wouldn't be classified as 'one-way suicide' certainties. The only way people can survive in space or on Mars is if there is the whole of Earth's backing behind them. No Earth, No Survival.

&quot;Everyone agrees that we should try to avoid extinction&quot;<p>Perhaps I&#x27;m an outlier here but I don&#x27;t see why we should do anything in particular to ensure the survival of humanity.

no. we should use our knowledge to harden our planet against our kind so that we can have security and longevity to develop real space faring tech

Yes.
