Important topic, absolute garbage article. It's more fiction than facts and 1. on hn ofc because the headline sounded nice. I get the intention of exaggerated fiction and landing on what is happening now or before but that's propaganda 101...FUD at its best. Disgusting.
Obviously everything that's in the future is not a fact - or "wildly speculative and hypothetical" as the article itself puts it. See it as a call to action to ensure that it remains fiction.
Call to action? The author did nothing to encourage engagement on the topics only on his article. No information about how you could get active yourself or how you could approach the topic politically just FUD.
They were calling attention to the problem, not proposing a solution. But calling out a problem is a call to action for people to try to come up with a (or multiple) solution.
Just because there isn't certainty that it would happen like this, doesn't mean there's not a possible future that looks somewhat like this. Nothing that was listed here seems particularly far-fetched to me, I don't think.
Done. So they're calling out things that could happen, driving the point home by placing them in a timeline. That makes the issue top of mind again for people, potentially spurring them into action - even if just by e.g. making it one of people's considerations in their next election.
