Absolutely, internet anonymity has made it so much easier for people to "unleash" their dark side...
I totally agree, if fact way back in 1994 I did a social commentary painting, "Incommunicado " (2 row, far right- swimsuits with pagers) about that very subject.
My comments from the painting... "In the time of the ancient Greeks, runners would traverse great distances in order to bring the outcome of their army’s battle to their King. With the news of victory, the messenger would be heaped with honors whereas news of defeat would…, well you have to wonder why those runners just didn’t kind of get lost in route. Ever since then the world of communication has traveled in two different directions; to make information arrive faster and to deliver it at a safe distance.
Jumping ahead 2000 years, we arrive at the Information Age. First, there was the telegraph, which led to the telephone. Information arrived quickly and at that safe distance but the problem was people weren’t always around to get it. This gave birth to the answering machine which begot the pager which begot the cellphone which begot the cellphone-pager-emailer.
These advances in technology have now led us now to become prisoners of communication. Where it was once enough to check for messages once a day, now we’re expected to check them at least hourly. We get information emailed to us for information’s sake. It’s a wonder anybody gets any real work done any more.
Our messaging is delivered at a safe distance but it’s also becoming more and more distant. Not having to face one another allows our petty traits to shine through in email and hollow recordings on answering machines. Humanity has truly become roadkill on the information superhighway."
