I'm sorry if this is offensive, but is this satire? The responses seem genuine but OP's username is "obviouslyfake" and the username is brand new. I don't want to be insensitive if OP is really depressed. But the tone seems sarcastic to me? I could certainly be wrong, but it seems like they are poking fun at other use cases of "AskHN."
Why is this necessarily so? If something is self-evident, does that prevent one from commenting on how we arrived at that state? The author is not trying to convince the reader that it is axiomatic that the world has become like sf. The author is telling a story about how the world has become like sf and how the world has the potential to become like climate change sf (or already has).
