Computerizing people may be next step in tech 13 years ago
I think that most people can agree on the fact that this type of technology holds much medical promise. The public will most like have concerns about its other applications. At what point is line crossed between medical need and bio-curiosity? Is the privacy risk worth some neat statistics which may or may not improve the users health? These questions will become more relevant as accessibility increases.
As for the use of implants to unlock doors and so on, I find it discomforting. Applications such as this are too personal and do not provide enough benefit. Suffice to say that I will be holding on to my keys.
