As the field of implantable brain devices moves in leaps and bounds, there will come a time in the future when we will need to consider obsolescence of these devices, and as the implants grow in complexity and scope, will we eventually have to redefine our idea of what it is to be human?
Then we need to reconsider capitalism, because that system is dependent on you buying stuff repeatedly. I really don’t like the idea of a blind person getting their vision back only for that implant to fail.
