Earth has been quite obviously life-bearing for at least 2 billion years. We should have been wiped out long ago.
I believe the theory is that as civilizations broadcast a signal indicating life exists strong enough such that it is picked up by other civilizations, the dark forest theory applies. Essentially we haven't broadcasted a signal loud enough to be picked up
Let's be honest, Lemmy is not a good sample of the general population. We're all atypical in one way or another, it makes sense that niche extremism concentrates here.
I don't know much about this topic, but I'm seeing a lot of uncontested claims of "us spends more on healthcare per capita" in this thread, leading me to believe that more money won't fix the underlying problem.
Multiple people are calling out that the mine planet wasn't at 80% liberation while the child planet was at 45% - are you sure you didn't check another planet by accident, or otherwise mix up your numbers?
If you just take a look at the memes the community made you'll see that they're all focused on Helldivers saving the kids, which is further evidence that you might've gotten the numbers wrong.
EDIT: I haven't used this website before, but this dashboard shows that marfark was at 0% liberation until yesterday. I'm pretty sure you've gotten your numbers wrong initially. I think when you checked and the planet had 74k players, the liberation had RISEN to 39%, which is supported by the dashboard plot of marfarks liberationb& the timestamp of 2024-06-15T02:45:04Z shows 76k active players and around 40% liberation, steadily rising up from 0 before.
I think a day ago it was 40% kids planet and 0% mines, but I didn't make it a point to remember. I want to say it was 7k players on mines, and 25k on kids.
Informal, modern society understands it the way you do, the term is just different here on Lemmy lol.
