Let's put ourselves 20 years into the future. Without arguing too much about specifics, I think we can all agree that we will have computers that are much more advanced and complex than they are now. In addition they will be a much larger part of our daily lives.
What are the dangers/ implications/ awesome things that will result from our reliance and use of technology that we don't understand? Presumably you will need apple or google or whomever to service/upgrade/maintain your retinal implants, right?
Or will you go linux style and be "open-source" so you know what technology is running inside your body?
I for one am not eager to patch a driver for my ears so they can run on linux ;)
