A: People spend much less time reading books nowadays.

B: That doesn’t mean people have stopped learning new stuff. Books aren’t out of the picture, but they’re only one way of experiencing information in the world today.

Note: “Out of the picture” can be understood using the photo-taking analogy. After a group meeting or gathering, for instance, people often want to take a group picture to record and remember the occasion. On such an occasion, it’s important to make sure everybody is included in the picture. Metaphorically, if something or someone is described as “out of the picture,” it means they’re not involved in the situation. By extension, we infer that they’re not important.
