Given that the Human body can be adapted for micro-g (I certainly wouldn't bet money against it), and that suitable materials science developments will make radiation shielding no big deal, I can easily envision a Human diaspora all across the galaxy and beyond, with Humans adapted for the environments that they choose to live in, whether micro-g, rotating (or gravity tech) habitats or gravity wells of widely diverse characteristic and atmosphere. Of course, our machines will both precede and accompany us on these adventures, but I cannot envision any future where Humanity will fail to be center stage in its' own odyssey, and certainly not one in which we will apathetically remain behind while our 'heirs', the machines, go out and colonize the stars.

A human diaspora beyond the galaxy? Unless a new paradigm in physics is created or we say, manipulate a star/solar system into a rocket (ie direct a stars energy in one direction) and slingshot out of the galaxy and toward another galaxy. (Which would still take say 100 million years to traverse, and entail fantastic abilities to manipulate a star directly, not to mention keeping the human or robots surrogates on task to keep the star going to the target galaxy.) It is very far out for human endeavor, especially considering how much space in our own galaxy we have to work with.
