There's no such thing as a "finish line" for humans, we always come up with something new to chase - take one's stacking-goals as an example.
I'd like to live long enough to be able to take advantage of the next big breakthroughs; maybe we will find a way to make humans immortal one day - that is, Immortal as in not dying because of cells not renewing themselves, thus theoretically being able to live for hundreds of years, or maybe through means of the necessary technical implants, turning one into a cyborg.
I'd really love to witness the age where humans turn into Gods.
