问答题 1.  We travel more eagerly than ever, but fewer of us end up seeing things with our own eyes. Take yourself to any place of beauty, or any event that draws a crowd. Look around and you'll see a solemn-faced, dull eyed crowd with one arm collectively raised in religious devotion. Each hand clutches a phone and each phone functions as camera. People are focused intently upon their phone screens: even when only meters away, they fail to see with their own eyes.
    We do sometimes benefit from the filming of some event that would otherwise have no objective record. But these videos are a tiny fraction of what's being recorded every hour, every minute, every second worldwide.
    One of the disturbing effects of people's filming mania is the establishment of a boundary between themselves and the events unfolding, transforming them from present witnesses to mere camera users. Since their eyes fail to see the action directly, they are in some senses not really there at all. In thinking of their film's future, the present moment passed them by.
