Genetic modifications can't alter human nature. What you'll have is a different species, closely related to humans. You can argue that's just semantics, I can agree to a point but unless you give a proper answer to what does it mean to be human my criticism is still valid.
As long as we're going to argue semantics, a "species" is a set of animals who can reproduce with each other.
Dogs are all still dogs, despite the massive genetic changes we've imposed on the various breeds. They can all still interbreed.
I really don't expect humans to accept genetic modifications that make their offspring reproductively incompatible with the rest of humanity. So speciation seems unlikely.

There are genetic differences between different human races... not to mention constant mutations.
