Background to this slightly weird question: I found one of my old an English exams on science fiction and dystopian literature from the 11th grade in North-Rhine Westphalia, Germany (ca. 2004) and found a similar question. The idea back then was to discuss the pro- and cons of a BCI (and I objectively did not do to well back then) . I am interested about people’s opinions.
Judging by how tech has basically used it to spy, control, and advertise to people, there is no way I would let more of my data get in the hands of these ghouls. The only way this could happen is if there were stringent government controls that put the ownership of data into the hands of people with walls around that data preventing governments from accessing it. At this point, none of this seems possible.
