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.
