great write up, the term cyborg reminds me of Van Dam old movie titled Cyborg. I always love this part of technology but what people fail to realize or the question we are not asking ourselves is, can we contain these machines if they misbehave? Watch terminator movie series and you'll understand what I am talking about. Nice write up and I would love to research more on the BCI you mentioned earlier and if I find something worth sharing with the community, I'll do so with your permission.
