How to not be depressed that the world is doomed
This was the search engine query that landed some troubled (I imagine) soul on these pages, probably reading this post.
I don’t have an answer to your question, seeker, save to say that the world will survive us. Humanity may be doomed but it will have been a fun ride, and the world will outlive us and maybe sprout something new and intelligent in the future. Each one of us is doomed too, eventually, but we may as well make the best of what we’ve got.
That, and knowledge. And beauty.
