I think his goal with space colonization is more in line with jump starting the centuries long process of terraforming planets like mars, Venus etc and colonizing space.
There certainly is a long term need for it in my mind. It won’t be completed in any of our life times but the start is just getting there.
There will be no terraforming. It takes too long and too much energy. Its easier to do much greater works in way less time. Venus we would have to remove most of the atmosphere and somehow cool it way down. Mars will never have a magnetic field required to keep an atmosphere from blowing away and to keep you safe from radiation and will never be a good place to live or harvest for resources.
Yea, as of today this is true. It’s a process that will take centuries. We already have theoretical formulations in chemistry and materials science to terraform The Venetian or Martian atmosphere. The biggest issue is getting the technology scaled up and transporting it there in a large enough scale.
With centuries of time and advancement in automation and space travel, I do think we can terraform a planet. It’s really the only viable option for a long term, self sustaining ecosystem other than earth. We may have to solve the terraforming problem to save earth it self in light of some future hypothetical calamity, anyways.
Even though Venus’ atmosphere is some 90 times as dense as earths, it is still the more viable candidate for long term, self sustaining habitation if terraformed, IMO. It has nearly the same gravity as earth as well as an active core. Everyone is fixated on Mars right now, and as a base or short term solution, it is viable, but the effects of low gravity on life would be great in the long term, and life may not exist as we know it, or at all there.. A fully manifested atmosphere would take millions of years to strip away by solar winds, even with no magnetosphere, and there are artificial solutions, as well. Again, the biggest issue is scaling up and getting the equipment there.
Given centuries of time and advancement though, I do believe we will see terraforming of one or both in the next several hundred years or millennia.
No one knows for sure though, and anyone saying anything with certainty is just being short sighted.

This channel is amazing btw
