ignoring what you said, I'll go by my assumptions of what you mean (How could we make humans better vs. how evolution will change us)
We'll be taller, and hairless. Better at 3D manipulation in our heads, with much skinnier and pointed fingers (For more detailed work) Either duplication of many organs (Primarily the heart) or preferably a mechanism that automatically replaces the insides of the body every dozen years or so to like new conditions. Removal of cancer, mutations (For if are in complete control of our genetics evolution in the forum of natural selection is pointless). one new eye, on the back of the head (So we can see behind us, but no depth perception as if we need it we'll use our better front eyes) removal of fat build up (hello skinny people), protection of the eyes, better eyes in general (Improved night vision, better color differential, and better range in the wave lengths). Also a computer in our heads, so that we learn ow to find information, not just learning the information (Which is essential as we have so much information). Tougher skin, with no pores.
In our logic: Dramatically decreased love drive and desire for power/wealth. Dramatically increased positive response to accomplishment and helping others. somehow force people to see everything brown townytically.
Theres more to add.
