> And so, slowly, we boil. Climate changing power, without the wisdom to wield it, is as plausible a Great Filter as anything. Hard to develop a space program when you're spending all your production fighting over scarce resources, plugging leaks, and attempting to feed a planet with decreasing yields. https://en.m.wikipedia.org/wiki/Great_Filter
I had two daughters before I came to the conclusion that this is the most likely path for humanity at this point. There is a possibility of a global awakening that might prevent this tragic loss of megafauna. But I'm already a vegan and don't drive much; can't think of more to do, and while I'm not too bad at dealing with this, it can be quite depressing.
Our society, and our civilisation is going to change, in massive ways in the coming century, one way or another. And all of us are going to live in less luxury than we do now - simply because such luxury is unsustainable. But it doesn't mean or children are all going to starve or drown.
We don't know what the future holds. Go back to the boundless optimism of the fifties, where everyone thought we'd live on the moon by now, drive spaceships to work and have robot butlers. I feel like today some of us are at the other end of the spectrum, in boundless pesimism.
Do all you can to pollute less, and encourage those around you to do the same. Drive less. Don't fly. Buy second hand. Replace your oil boiler. Grow veg. Write to your representatives But don't give up on your children's future. Just because the world of their twenties won't resemble yours, doesn't mean they won't find happiness. In 30 years the world could be ugly by todays standards but you and i and our kids will probably all still be in it.
And for your own mental health, don't let HN comments drag you down. I've seen people on here literally advocating suicide over this issue. We as tech heads are typically of a personality which is susceptible to these negative feedback loops, and reading posts on here can break a person. I'm breaking my own rule today even being here but I'm feeling good for once and wanted to spread it.
Be well, have fun with your daughters, watch them grow up.
