Humans aren't really evolving much anymore...we mix our genes all across the planet and due to medical technology "natural selection" doesn't come into play too much.
Evolutions doesn't stop, just because we can don't abandoned the weakest member of our society. Humans still evolve to day, the gain of blue eyes happen around 10k years ago, and we are a couple of hundreds from losing them. Why?
Evolutuion! Evolutions is
all living thing, no matter how smart we think we are, and no matter much the natural selection now is a sideshow, for the most part.

I doubt we'll hit a point where we say "Hey we are completely genetically different from humans of X thousand years ago"
This will never happen, all living thing on this earth, share some genetic material. So no we will never say ``completely´´ but we (hopefully) will hit the point when we will say. "Hey, we are no longer homo sapiens." But I still think we will call ours self humans.
