I think that rather than trying to discover the meaning of life while we're busily burning fossil fuels on a single planet that we'd be better off punting on the issue until life in general, and humans in particular, have managed to sustainably spread beyond Earth (and of course demonstrate better care-taking of the world we do have). Until we achieve that end, Camus' philosophy is useless, and in some cases actively harmful.

(Once we're on a few tens of planets, navel-gaze all you want.)
