So I spotted this and wondered how such a complex society gets by without writing. But it according to this[1] at least it seems they did have some form of writing through hieroglyphs.
Even still, I wonder if we can learn anything from societies with simplified forms of written communication and how they organised. Things that could help us organise better now and reduce the information overload that occurs within large orgs or projects (email, requirements docs etc).
For example, maybe we could use Standardised hieroglyphs to describe a users interaction with an application. It would enforce simplification and assist with compiling from requirements through opinionated frameworks. Plus it would be prettier than your standard Jira ticket :P
