Darwin's Theory of Evolution and humans(details)?

I have been thinking that do you believe evolution has taken a “pit stop” on humans?

I mean technically we should keep evolving to become better faster,stronger,smarter right? I keep imaging what we may be like in say 100 years or even 1,000. I imagine so mixed and versatile that the likes of race and background become very…mixed or blurred together,but would be better?

That is the basic ideal of it I believe…..But it seems maybe we are on the top of the food chain? but really it seems we have sacrificed physical aspects of nature for more intelligence?

Do you think evolution finally began to experiment or understand that if you have the knowledge or can manipulate the world that you can do far more or be superior to anything?

Also are humans on the top of the food chain? How do we appropriately decide where humans fit into it, as we seem to able to kill anything but not naturally per se with our own abilities(I hope I made sense)

Thank you for any insight on these things.
