Before the internet, people could already chat. It is a topic that has always intrigued me: how was it possible? As a kid I had already heard about a command called talk, and the most impressive part is that you can still use it today, with no sign-ups and straight from the terminal, even in workplaces where I work over a VPN. It is not dead: it is just that few people know its potential.
