Over 90 Percent of the World's Data Was Created in the Last Two Years
Humanity generates approximately 2.5 quintillion bytes of data every day. The explosion of smartphones, IoT devices, social media, and cloud computing means the vast majority of all data ever created is less than two years old.
Why It’s Fascinating
It means our digital footprint is growing at a rate that dwarfs all prior human record-keeping combined. Every two years, we generate more data than existed in all of previous human history. Storage, energy consumption, and privacy challenges grow exponentially as a result.

There Are More Possible Internet Addresses in IPv6 Than Atoms on Earth
IPv6 supports 340 undecillion unique addresses (3.4 x 10^38). Earth contains roughly 10^50 atoms, but the number of IPv6 addresses per square meter of Earth's surface is still about 6.7 x 10^23 — Avogadro's number.
The First Computer Bug Was an Actual Bug
In 1947, engineers working on the Harvard Mark II computer found a moth trapped in a relay, causing a malfunction. Grace Hopper taped the moth into the logbook with the note 'First actual case of bug being found,' popularizing the term 'debugging.'
The Entire Text of Wikipedia Is Only About 22 Gigabytes
All of English Wikipedia's article text, compressed, fits in roughly 22 gigabytes — small enough to fit on a basic USB drive. The full database with edit histories and metadata is much larger, but the sum of all human knowledge on Wikipedia is surprisingly compact.
