Hi, "we now differ greatly not only from our ancestors of ten million years ago, but even from our ancestors of a thousand years ago". In what way do we differ greatly from our ancestors of a thousand years ago? (I just don't see it.)

The problem with letting populations leave earth and settle the galaxy would be a real one and not a question of “earth partiality” in the sense of narrow self-attachment or nationalism - as Robin describes it here. This misses the actual risk.

The real problem would be that they grow distant from us culturally and/biologically (with communication limited by speed of light). And then they are effectively aliens (after a few thousand years) and may well come back and kill, conquer or enslave the population of earth.

This is the same problem with AI.

The fear is not that they outcompete humans and peaceably replace us with a new and more effective species. I agree this would only be sad to the degree that you are emotionally attached to humans. The fear is that we (or our children) or humankind are slaughtered, or thrown into desperate misery and hunger - mostly as some sort of collateral damage to another species’ expansion.
