As a writer for the Guardian explained when he downloaded his Facebook data (something anyone can do) his data download was nearly 600 megabytes - equivalent to nearly 400,000 Word documents. Experts estimate that there are 2.5 quintillion bytes of data created each day at our current pace, a figure that continues to grow. Thanks to social media, the data collected on the most mundane details of daily life is unprecedented. But that won’t be true for future historians: assuming an apocalyptic event does not wipe the internet off this plane of existence, or some sweeping data privacy legislation mandates widespread deletion, humans of the future will know a great deal about us. We only have journals and old photographs to piece together stories. Little is known about the interior lives of regular people who lived centuries ago, mostly because the internet did not exist.
