Technology gives us the facilities that lessen the barriers of time and distance - the telegraph and cable, the telephone, radio, and the rest.
The major advances in speed of communication and ability to interact took place more than a century ago. The shift from sailing ships to telegraph was far more radical than that from telephone to email!
Science, as illustrated by the printing press, the telegraph, the railway, is a double-edged sword. At the same moment that it puts an enormous power in the hands of the good man, it also offers an equal advantage to the evil disposed.
When we developed written language, we significantly increased our functional memory and our ability to share insights and knowledge across time and space. The same thing happened with the invention of the printing press, the telegraph, and the radio.
I turn to the 'Telegraph's' obituaries page with trepidation.
People always think they're in the middle of a revolution while they tend not to realize the enormity of a change that has happened in the past. The telegraph was a revolution, but who looks at it that way these days? The telegraph sped up the transportation of messages over long distances by a huge factor.
As to Bell's talking telegraph, it only creates interest in scientific circles... its commercial values will be limited.
One of the ways the telegraph changed us as humans was it gave us a new sense of what time it is. It gave us an understanding of simultaneity. It gave us the ability to synchronize clocks from one place to another. It made it possible for the world to have standard time and time zones and then Daylight Savings Time and then, after that, jetlag.
Communications devices were always used to effect change, to effect revolution. Telephone, telegraph - these all seemed like very big enhancements at the time.
I have managed to infuriate the bank bosses; acquire a fatwa from the revolutionary guards of the trades union movement; frighten the 'Daily Telegraph' with a progressive graduate payment; and upset very rich people who are trying to dodge British taxes. I must be doing something right.
