We'll still evolve, it's just adding variables, which when compared to the timespan evolution occurs throughout, seem trivial.
Not only the grooming of genetically defficient individuals but also the chemicals from pollution, food additives and preservatives, chemicals in our drinking water, changes in the ecosystem surrounding us, changes in our lifestyles (no exercise, bad diet, etc.). It seems to me that all of these things are factors that we should be concerned about, but at the same time who knows what could happen over millions of years.
My guess is we won't last long enough to reach the point of being considered a whole other species anyhow. We're just going to be another dead branch on the tree of evolution.
Maybe chimps and smarter apes will survive and eventually turn into something better than humans, who knows.
Now I'm gettin all planet of the apes on your asses.

I see you there lurking on the periphery of my vision.
But when i try to look at you,
you scurry away.
Are you shy, squiggly line?
Why only when i ignore you, do you return to the centre of my eye?
Oh squiggly line!
It’s alright;
You are forgiven.”
