We had a good run. Good luck to the next species to dominate the earth. May you avoid religious dogma, find an economic system that respects your natural environment, and a political system that respects the right to live a clean and healthy world.

Mosquitos are like “that species was delicious. I wonder what the next one will taste like”

we probably taste like shit.. they sit around the campfire and remember the good old days of fresh, free range Dino blood as far as the proboscis could poke.. not this Walmart meat they get now..

We had a good run.

Did we, though?

We created a lot of value for the shareholders.

Depends on how you quantify it. We sure did make a lot of money, or at least the winners did.

I mean, we left the planet. We created art. We did some good, and life will diversify again after we're gone.

and life will diversify again after we’re gone.

Here's hoping; but that's far from a safe assumption. The kicker about the changes we're making to this planet is that a lot of them are positive feedback loops, so even if 100% of humans just got thanos-snapped out of existence RIGHT NOW, meaning a complete stop on fossil fuel consumption, deforestation, etc; the damage we've already caused will continue to get worse on its own with no further input from us.

So how far can those feedback loops go until they're broken naturally? They might stabilize; they might just carry on until this planet is molten.

There will for sure be life after the last human dies, but given a few thousand more years, even the most resilient of critters could still be fucked because of us.

they might just carry on until this planet is molten

The odds of true runaway warming are very low, the planet has both been much hotter and had much higher CO2 levels in the past. The Holocene is actually a cool period, geologically.

We're just going to make it too hot to grow enough crops to feed the world.

it seems pretty likely that microprocessors will survive us, and give a BIG jump start to any species that follows. literacy seems to be a longer shot, but still a possible stepping stone for some other organism to take over our work. my money is on fungi to figure out microprocessors. if not them, then plants, especially "weeds". finally, ocean mammals might be able to work some of the junk we've made and cargo-cult themselves into the information age.

i really am hopeful for life on earth to survive the death of Sol.

we did just waste a good few million years of evolution though (let's say 65 million accounting for the rise of mammals). earth isn't going to be habitable forever, from memory there's less than a billion years left before the temp would increase with the expanding sun enough to make liquid water impossible. feels like we kind of shot earth in the foot a bit here

65 million years isn't that bad on a geologic scale

As long as there isn't a runaway greenhouse effect that turns Earth to Venus, life would almost certainly continue, with or without us.

Did you do any of these things yourself?

Is there any reason you would think me not producing art means that humans haven't?

Maybe he's a master in ASCII art, what do you know

There were a couple of hundred thousand years of humans managing not to fuck up the entire planet, before the two centuries of doing so for the sake of money.

There were periods in which we were nicer to the planet, but we've always been pretty horrible to each other. Even at the stage of civilization we're at now - with all the advancements and comforts etc - we're still going to war with each other just for the hell of it; murdering each other over shit like skin color or what we find sexually attractive; not only profiteering off the suffering of others, but actively manufacturing suffering to profiteer off.

We really are horrible.

We also managed to kill off almost all the large animals thousands of years ago, come to think of it.

Realistically, extinction would be sweet relief compared to what is actually in store for humans with climate change. More likely that we hang around in smaller communities and death / suffering is even more widespread.

I mean realistically it's all going to hell sooner or later. You'll start with millions of climate refugees, closed borders, violence. Then climate wars (a wall with machine guns isn't going to stop people who have no other way to survive). And if a country with nukes (like India) finds itself uninhabitable then things are really going south. Next up you have a possible nuclear war and the end of humanity as we know it.

Sure, a small amount of humans might survive, but civilization will go down in chaos. Even areas that are inhabitable and have plenty of water will break down, because the local infrastructure can't support hundreds of thousands of refugees forcing their way in.

You’ll start with millions of climate refugees

Millions? If only.

I've seen estimates which say at least a billion by 2050:

https://www.weforum.org/agenda/2021/06/climate-refugees-the-world-s-forgotten-victims/)

Oh, I was more thinking per area. Not all refugees will go to the same place.

It will start with millions and that might already be enough to cause collapse. When it's over a billion it's already over.

The whole Syria thing already caused us lots of issues in Europe. Arguably the civil war was caused in part by climate change exacerbating a drought. The surge in refugees helped the far right and populists across Europe and was a factor in brexit.

I can only imagine what'll happen if it gets worse. Children of Men is likely to be eerily prophetic.

I've seen estimates that say a billion dead by 2100 is the most optimistic possible outcome. Even the notoriously cautious IPCC is making the most unimaginably dire predictions:

In its report focusing on the impacts of global warming on people and the planet, the Intergovernmental Panel on Climate Change says that every inhabited continent is already experiencing multiple climate impacts, from droughts and flooding to biodiversity loss and falling food production. Between 3.3 to 3.6 billion people live in areas “highly vulnerable to climate change,” the authors warn, with “additional severe risks” should the Earth warm beyond 1.5 degrees Celsius (2.7 degrees Fahrenheit). (From an article in Forbes magazine.)

I wonder if primates are incapable of building a global economic system that doesn't end in disaster
