Interesting reads! Apologies, that's not what I intended to communicate, but I can understand where that conclusion came from.

I think understanding and exploring the universe is an essential "success metric" for intelligent life like humanity -- but I don't think it's at the expense of all else. I mentioned it because it, to me, makes a humanity that abandoned complexity a "failed" humanity. Although again, on an individual basis I think this is a fine option.

An underlying principle I believe in is an avoidance of waste. It's this principle that underpins part of why I think there is an obligation for humanity to understand/explore: to avoid wasting our improbable "gift". This principle constrains the principle of understanding/exploration and relates to Earth. Earth and life on Earth is itself rare and the result of its own biological lotteries. To blindly exploit Earth's resources is not only wasteful but shortsighted as well towards humanity's own survival. So I think I'm in stewardship on that spectrum, but need to sit with it a bit more.

With regards to the first article, I think it outlines many of the complexities around humanity's space travel and habitation. For me, the key bit is understanding and exploration; ie the seeing/understanding of what the universe is/has (on Earth as well as elsewhere). I don't actually think this has to be humanity. I think more broadly the obligation I've mentioned lies with intelligent life not necessarily humanity (we just happen to be the only example of such we're aware of). Habitation isn't as big a piece for me. If we can send robotic "eyes" for intelligence to see through, or if we create other intelligent life with different properties from humanity that can see/explore, I consider this goal met.
