"Always bet on text" is a good philosophy that I *almost* buy, except for one thing:
I'm yet to find any reasonable plaintext representation of graphs. Text can do trees just fine, but trees are inherently limiting. If there's no efficient notation for DAGs and graphs with cycles - i.e. structures that can't trivially be flattened without duplicating nodes - then text itself is heavily limited as a tool for thought.
Anyone knows of any interesting work in this space?
