As a species, we tend to think that evolution is the kind of thing that doesn't happen to us, there are those who even think that it might have stopped altogether for humans. If we do try to imagine what the next step in our evolution might be, we quite often fall into the trap of imagining that our hands might turn into cupholders or something, but this is a misunderstanding of how evolution works.
Evolution isn't "goal based", rather, it's mainly based on whether a mutation increases your chances of either getting killed, or getting laid. Humans do have another string to their bow though: Technology. It is thought that our ability to manipulate our environment and even our bodies could seriously mess with evolution as we know it.
Seeing as evolution is such an unpredictable process, it's pretty difficult to imagine what will happen to us 100,000, 500,000 or even 1,000,000 years down the line, but we can have a good guess anyway.
