Unimaginable large scale of data

20 years ago, the electronic medical record was a novelty, and digital music was just a fantasy, and the word Twitter simply referred to the chirping of birds, and Google co-founder Sergey Brin was only a summer intern for Wolfram.

20 years later, the information revolution has brought tremendous changes to our lives. From the intuitive figures, the size of large data has been hard to imagine. According to IDC, a market research firm, people in 2012 created 2.8 ZB (1 ZB is 1 TB 1 billion times times) of data information. In 09, this data was about 0.8 zb,2011, which was 1.9 ZB.

Wired sums up some of the most interesting data in the world today:

In this big data age, the information explosion is unavoidable, and the amount of data that people create in 2020 is expected to exceed ZB. Today, people may create thousands or tens of thousands of petabytes of data (1 PB is 1024 TB), and one of your comments will be a very small part of that.
