But one thing that separates BCI from everything is the implant itself. Sure, people have addictions but they also have that choice of stop doing that and focus on things that are important to that person (I know that overcoming addiction is way tougher than just writing about having choice as I'm still going through it at the moment, but one can surely get out this). The thing that differentiates this from earlier technological advancements is that now there is some hardware directly wired in your brain whereas previous technology was outside of your body and I don't think that I would able to accept that without having an impending worry about implant having access to my brain directly.
