The Digital Age
In fifty years computers moved from air-conditioned rooms to pockets, and networks made copying information almost free. That one change rearranged work, money, news and privacy, and the arguments about it are still open.
What a learner can do afterwards
- Put early computers, personal computers, the web and smartphones in order and say roughly when each arrived
- Name one kind of work the network created and one it removed
- Explain what changed once copying information cost almost nothing
- Give one cost people argue about now, such as privacy, misinformation, or a few firms holding most of the traffic

In fifty years computers moved from air-conditioned rooms to pockets. The first machines filled whole rooms and needed teams of engineers. By the 1970s and 1980s personal computers sat on home desks, the 1990s web linked them across the planet, and in the 2000s smartphones put all of it in your pocket.
Networks made copying information almost free. A message that once took days to mail can now reach millions in seconds, and news, lessons, chats, and video calls travel instantly. But false claims travel just as fast as true ones, which changed how you should read everything.
Work changed with the wires. Building and running networks created jobs for designers, server keepers, and security guards, while mail sorting, telegraph work, and much print shop labour shrank. Security means keeping your data safe from intruders, while privacy means deciding who may see it in the first place, and firms often want more of your data for the first while you want less stored for the second.
Power did not spread evenly. A small number of big platforms still decide what shows up first in your feed, and in 2014 one firm quietly tweaked almost 700,000 feeds to test moods. When one company holds billions of users, its ranking rules can shape feelings, opinions, and even elections.
Machines shrank into pockets and copying went free, rearranging work, news, and privacy while few firms kept the traffic.
