Earlier quoted context omitted.
For instance, maybe I'm in class, and I get an extremely important email and need to send an immediate reply. Maybe I'm a working-adult student and my babysitter has just IMed me. Maybe I manage the campus newspaper's website and someone just sent me a report of a critical bug that I need to deal with right away. This isn't strictly a reply to jawns, but it's on a related topic that I've wondered about. Fifteen years…
A few hundred years ago, nobody expected to go anywhere faster than a horse could take them there, why must we go faster now? Life changes. If people don't like that, there are still some very nice remote forests they can go live in.
I guess I still retain the wondering, though; with possible response times reduced to effectively instantaneous, are we losing anything? Is it good that anything we are doing can always be interrupted by something else?
