The Web Runs Out of Disk Space

At the start of the decade, the total storage required for every web file was estimated to have reached five zettabytes. Within a few years, the world will be generating fifty zettabytes of data every year. A zettabyte is one billion terabytes -- or 10²¹ bytes. It's a lot, and hard disk manufacturers cannot keep pace with demand. The numbers are not surprising when you consider more than four people are born every second. This is significantly higher than disk drive production. The 50Zb estimate would be exceeded if everyone on the planet uploaded just two photographs annually. I interviewed Prof. Ali Lo who heads the Taskforce Utilizing Redundant Disk Space:

The web is at crisis point. It cannot cope with the sustained influx of new data. We have deleted temporary files, backed-up to the cloud, archived to DVDs and defragmented several times. Nothing helps: every byte is used the moment it's freed.

Web Usage Breakdown

Sir Tim Berners-Lee devised the web to share research information in hyper-linked documents. Within twenty-five years, it now consists:

• 28.65% pictures of cats


• 16.80% vain selfies


• 14.82% pointless social media chatter


• 12.73% inane vlogger videos


• 9.76% advertising/clickbait pages


• 8.70% scams and cons


• 4.79% articles soliciting spurious statistics


• 3.79% new JavaScript tools/libraries


• 0.76% documents for the betterment of human knowledge

Prof. Ali Lo stated:

There are now more pictures of cats on the web than there are cats.

Social Media Stockpile

The success of social media has exponentially increased data usage. People are expected to document their daily routine with comments, photographs and videos. Much of this content is never viewed by anyone but it remains stored forever. If a post does go viral, the same data is replicated thousands of times by different people across different networks. The situation will worsen when Facebook's Fetus project is launched. The ambitious service will automatically open an account, record a timeline and send status updates before you are born.
