A New Mode of Cancer Treatment

If 2023 ends up giving us AGI, room-temperature superconductors, Starships and a cure for cancer, I think we will able to call it a good year...

I think humanity deserves it after so many consecutive weird years

I doubt the extinction of the human race via a runaway technological event will turn the planet into a wonderland paradise for the rest of the species that inhabit our planet.

The planet itself, being a rock, doesn't care, at all.

We're as much a part of the planet as its rocks, and we care. You could say that your bones don't care, but the organism that is you cares. In the same way the planet cares through the subsystem that includes us even if its rocks don't care.

You're right if you define a planet as its rocks, and would also be right to assert that humans don't care if you defined a human as its skeleton.
