I think that in any comprehensible time scale, accelerationism is an inevitable outcome rather than a desirable outcome. I can see a conscious set of lifeforms that would prefer to burn slowly and enjoy existence in a relatively sustainable manner. It does however seem inevitable that life will -- if it does not fail completely -- spill out of our planet into the universe as you say in the form of machines or 'AI', rather than meatbags. Life is a game with winners and losers and winning is selecting for superior reproduction, technology, and colonisation.
