Anecdotes
The invention of the telegraph sent the information people wanted to send to distant places at a speed of 300,000 kilometers per second. This is an epoch-making initiative in the history of human information. But over time, people became a little dissatisfied. Because to send a telegram, you need to draft the telegram first, then translate it into a telegraph code and give it to the telegraph operator to send out. After receiving the message, the other party's telegraph operator must first translate the telegram into text and then deliver it to the recipient. This not only involves numerous procedures, but also prevents two-way information exchange in a timely manner; it takes a long time to get a call back from the other party.
