I saw this graph and found it strange that cars have needed to become so much bigger while everything else shrinks…
The other more intangible element is that flotsam of data that I have accumulated. 25 years ago it was a bit of Hotmail, now I have GB’s of BS; old group chats and jokes on Whatsapp, slide decks that no one cares about, photos and promo emails from 2014…
What else has had this disproportionate size change in the last 25 years?
