I think that with AI overtaking human intelligence is bound to happen it is just a matter of when. As they reverse engineer the human brain and discover more and more about human intelligence on the nanoscale. They will be able to build a intelligence without any emotional biases(that eat up processing power) like the human mind has.
AI with rights just like human beings, I'm sure a merging of humans with machine on the nanoscale will keep on progressing to the point of reaching some type of singularity it is just a matter of when and there is no turning back.
I kind of see it as a person choice some will not want to merge on the nanoscale but as time goes on they will be fewer and fewer because the advantages will out weigh the disadvantages by a wide margin.
