Tim Maly of Quiet Babylon had a series of articles around cyborgs in celebration of the 50th anniversary of the word. Personally, a lot of it was too abstract to be useful.
However, this essay from Eleanor Saitta, as part of that series, highlights some of the points and ends in a for me quite thought provoking conclusion:
The old cyborg is a disconnected, technological powerhouse, and one was worried with how a cyborg’s humanity would be affected. Now we realize that the more common form of cyborg is the networked human, using technology to extend its senses and thoughts across internet. What effects will that have on humanity? When nothing is hidden, everything is shared, opinions and half-truths everywhere. Perhaps that will be much more challenging to our feeling of humanity.
