As much as I claim to be a luddite and technoclast in many regards, this particular comic calls my bluff with regards to communication. While I do occasionally write and send letters for the anachronism of the action, I more often scribe a quick email with all its informality. There are multiple reasons for this, but it boils down to the speed at which a response can be obtained. While email is not realtime, it is very nearly realtime in some instances.
It is amusing that the dire predictions from over one hundred forty years ago have not came completely to pass, but many aspects are true.
