Titus mentions the lack of need for a picture like the one he sees in the hospital. What does this say about Titus' imagination?

Titus is fed information from the feed at all times. He, and his teenage friends, have no need for imagination, as they can have nearly everything they desire. They are trained, through the feed, not to think, but to respond. Thus, when faced with a picture that has no past or future, he is unable to find a point to it.
