Nostr isn't moving fast enough to guarantee it stops climate change from killing everyone, so you can't guarantee it will fix these problems by helping everyone live to see a better future.

Nostr also isn't causing climate change, so even if you're anti-natalist and you think killing everyone is a solution, it seems like it would be a stretch to say nostr is responsible for killing everyone.

Thus, what you're saying here just sounds like climate denialism.
