Cedric,
I like you social commentary puzzles. We have a lot of room for many possible scenarios. One that strikes me here is that the bubble inverts the idea of the tiny space one is alloted in an airplane. One has , essentially, a tiny, dimly-lit, territory for oneself and one's neighbor. It's really an intimate endroit with a stranger.
Here, in the bubble, one is exposed to the world. Very different circumstances. There are now no screts possible between strangers!
