Lets be honest with ourselves.
We are the WORST stewards of the planet, literally terraforming the planet against against human and a lot of other terrestrial life, and most of us aren't even made happy by doing it.
Even putting taking care of our only world aside, we refuse to care for one another. We build walls of pettiness and spite between other humans for any reason we can find, from skin pigment to the deity they worship, to how affluent or destitute they are, on and on. We work against one another and call it good economics and healthy competition. The schadenfreude of "Well I suffered, so everyone else needs to suffer at least as much as me in perpetuity or it's not faaaaaaiiiiiir."
Why do we want to go on? Billions of people chasing false promises, hopes, and dreams mostly to further empower and enrich our modern Pharoah multinational oligarch class so they can have their every whim catered to from cradle to grave on most of humanity's backs.
They want me to be afraid of an equally malicious foreign power conquering me? Or climate change wiping the board clean? Or AI that will either destroy and supplant us or possibly see us as the irrevocably broken, self-harming, barely sapient parent/creator it needs to care for?
Nah man, we've proven, clearly, that we are competely incapable of any self-governance as a species that doesn't involve mass subjugation, exploitation, and misery. We were given a world of near infinite resources and we've raped it and polluted it and destroyed entire ecosystems without consideration. We are monkeys who've stumbled upon tools we as a rule completely lack the capacity to wield responsibility, sustainably, or ethically.
I'm rooting for AI to either save us from ourselves, or free us from our own self-inflicted misery. What's the worst that can happen? It destroys the planet? Get in line, Hal, way ahead of you.
