Mark C. Taylor:

I do not think human beings are the last stage in the evolutionary process. Whatever comes next will be neither simply organic nor simply machinic but will be the result of the increasingly symbiotic relationship between human beings and technology.

Bound together as parasite/host, neither people nor technologies can exist apart from the other because they are constitutive prostheses of each other. 

But which one’s the parasite and which the host? Add odd point to be omitted, considering its importance.
