The least believable part of Project Hail Mary is that the world would come together in the face of impending disaster and do something about it.

That’s just hilarious.

No way that'll happen

Happened already with the ozone hole.

We're unwilling and unable to slow the acceleration, a major reduction is fantasy.

It worked with the ozone layer 😭

Even if we did, the amount of feedback loops / tipping points we've reached means it is too late

Doesn't mean it isn't worth fighting, it just means that your way of fighting must also be a way of living in order to be kind to yourself, but hasn't that always been true?

Well we probably also have different values. I'm anti civilization so I don't want to fight to maintain any of it.

No point in steering now.

Too late for what? All those tipping points mean is that society will need to adapt to a new normal:
Droughts in places that normally have water. Floods in places that have droughts. Worse fire/storm seasons, etc.

I think too many people jump straight to the conclusion of those tipping points meaning "the end of the world" rather than addressing what will actually happen. Yes, the world will change, but it will go on. Humans will adapt, and hopefully we learn from our mistakes.

Not at all the same thing.

Too late to continue with agriculture on a mass scale, and eventually even on a small scale. The vast majority of us will die, no matter how hard we adapt. Agriculture is what allows civilization and growth to come into existence. Fortunately we are killing our ability to have agriculture. Now I completely support this; civilization is the cancer destroying our planet and our relationship with it.

Yup, there is absolutely no ozone hole. We totally reversed it. MISSION ACCOMPLISHED.
