One would think in a million years if we have that sort of technology, we would no longer be dependent on Earth for humans survival. Whether we would colonize other planets and make them habitable through terraform or build our own planets at that point.

One could imagine an "Earth 2.0" that we can move around the solar system, positioning it perfectly for the right weather.

That would probably destroy the solar system. Without the moon, the earth would just exit the solar system. Increasing the mass of earth by mining too much asteroids would cause the earth to fall into the sun. It’s a quite delicate balance.

Excuse me, what? Maybe if you somehow added enough energy to immediately jettison the moon from Earth’s orbit or steered every asteroid in the solar system into the surface of the Earth. This is just nonsense otherwise. Any future mega projects can easily account for orbital mechanics, it’s just physics not magic.

The mass of the moon is “not that much” on a solar scale. The comment was about adding another planet and moving it around the solar system to “adjust the thermostat.” We can’t even get a rocket off the ground without blowing it up sometimes… I have little faith that we can move a whole freakin planet around without killing everyone.

When you can tune the fusion of the sun using advanced particle physics and as of yet undiscovered branches of science, you don't need to move planets.
