That is it. When you become very aware of just how amazingly far away everything else is, fighting over a speak of dust and the only home we have seems absolutely ridiculous.

A great long form video on this is "Shouting at stars : A history of interstellar messages". It really highlights just how empty it all is. https://www.youtube.com/watch?v=uFI5WpK2sgg

You can't stop fighting the ones who claim the speck of dust (or a pale blue dot) is a flat disk.

If mankind exists in 1000 years time and hasn’t regressed then we’ll be able to build fusion powered self sustaining asteroids. Those can be used as airships to colonise every system in the Milky Way in a few million years.

600M years is enough time for Earth to try two or three attempts at intelegence, with full blown fossil fuel replenishment cycles. It won’t be humans - whether we leave for the stars tomorrow or blow ourselves to bits we’ll have evolved to something unrecognisable by then, but there’s very few things which could end life on earth in the next 200 million years (mainly very large out of system asteroids/rogue planets)

No rush then, modern humans aren't even 1m years old...

Being hippie worked in the 1960ies, a crowd with a similar mindset fared much worse in 1930ies Paris.
