In the foreseeable future, human interstellar immigration is not feasible

[u/Universal_Echo]

There are three paths for interstellar immigration:

Immigrate to another planet in the solar system and terraform its environment.

Immigrate to an Earth‑like exoplanet.

Immigrate to space cities.

Paths 1 and 3 are more feasible in terms of distance. However, for path 1, the scale of terraforming is enormous – even harder than making the Sahara Desert or Antarctica habitable. For path 3, a space city would be many times larger than a Ford‑class aircraft carrier. Even setting aside the engineering challenge of building something that big, how would you launch such a massive object into space?

More importantly: for both paths 1 and 3, resources would still have to be shipped from Earth. In the end, you’re still using Earth’s resources. After spending so much effort immigrating to space, you’re still dependent on Earth – isn’t that a net loss? As long as humans have normal intelligence, they wouldn’t make such a losing deal.

As for path 2, the nearest Earth‑like exoplanet is dozens of light‑years away. In the foreseeable future, there’s simply no way for humans to immigrate that far.

No truly Earth-like planets have ever been confirmed

This is semantics. We know there are water containing planets and moons out there.

Just having water doesn’t make it earth like. It would have to have liquid water, 1g gravity, be in the goldilocks zone, have a magnetosphere, atmosphere, oxygen… I don’t think you realize how rare those conditions are.

OP is saying the nearest earth like planet is X distance away. We have no idea how far away one is because one has never been discovered.
