What the question is asking is for an opinion on whether or not technology will replace books.
There is some room to interpret what is meant by replace. To me, 'replace' means nobody uses books at all, but I can understand your interpretation as well.
Since it's an opinion, there is no right or wrong answer, so that's why you're saying 'yes' and the other person said 'no'. You have different opinions, but both are valid. Your answers are also based on different interpretations of 'replace'.
