I've seen teenagers on the bus communicating with each other by
FarceBuke or whatever when they could just as easily turn their heads
and open their mouths.

Not a new thing. In the office where I was working in 2001, people would
email someone sat beside them, to ask when they wanted to go out to lunch.

It was less intrusive than interrupting their train of thought with a
verbal question.

Blimey, what were they thinking about..? Government policy..? (Sorry,
that just slipped out..)

I expect they were thinking about work.

The importance of "the zone" to productivity in highly mind-based work
(such as programing or engineering) is rarely understood by those not
experienced in such roles. Unfortunately, some of those people are
colleagues from another department, or, worse, management.
