Although your story starts off a bit rachety, it seems to have a interesting bit of plot behind it. Beware of settling in to a common pace of words; it masks tention and makes things seem boring. I love the phrase "This is useless... they don’t know about communicating anymore..." work a bit on atmosphere.

Interesting so far, but I think the whole thing would be better if you didn't jolt out the introductions to the characters. It seems a bit forced. Good diologe, though.
