The part where they deal with ethics (and all laugh at that girl that ended up being pregnant) was interesting, though unsatisfactory. Of course, awareness of potential dangers and being able to infer potential dangers is a good strategy in taking steps to protect oneself from the misuses and abuses of technology, but the fact is, that the person on the street has a whole lot of stuff to worry about, keep track of and manage. Given that these brain interfaces (and particularly brain interfaces developed for entertainment) would be built and marketed with profit in mind, it seems like transparency and pushing awareness of what the full capabilities or potential capabilities of these machines would be counter to the interests of companies that might produce these products. Ethics (and I am of course, speaking as someone who is not an expert in ethics) as applied to new technologies most definitely needs enforcement from legislation, though I really think that laws regarding technology and intellectual property need a comprehensive overhaul that will be able to level sufficient incentives not to misuse or abuse the technology by users as well as the producers, while still allowing a great amount of freedom to people interested in further developing applications for the technology in question. The point about technology and integration and the problems that the human immune system poses, is very interesting. It seems strange that technology capable of inferring a great deal about the physiological state is in the works, but I am curious to see how it goes and what the public's reaction will be, both initially and over a long period of time. It does seem kind of invasive, but ultimately of great use if implemented well. Another thing I'm curious about is how scientists are approaching how the human body might react to electrical impulses running within implanted devices, as well as how the people might deal with the degradation and maintenance of the devices. Cool stuff.
