If a useful brain-computer interface was available sometimes in your lifetime (and secure and safe) would you get one?

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.
