I would definitely not want this type of chip. Already I feel that I think too much and get headaches due to that. Hearing voices of other people would be too much.
If I had that chip I would feel like Edward in Twilight series. His head is always full of voices of other people and his tragedy is that he can listen to anyone except the one he loves. Imagine how he must feel when he can listen to anyone but not the most important person in your life. Thats tragedy all right.
Sometimes, we wish that we could listen to what others are thinking specially when your boss gives you an amused look and you think he’s cooking something in his brain. 😉
If we can get a chip which can be turned off and on according to your wish, that would be a dream come true. 😉
