Tool used: https://github.com/pavelfatin/typometer/ (run as java --add-opens java.desktop/java.awt=ALL-UNNAMED -jar typometer-1.0.1.jar

The idea and its representation are not the same thing.
That is why when you open large files - ST copes much better. Otherwise, there is no need to position Zed as a universal editor.
If the representation of the program code in the tree-sitter structure takes up less space than the source text, then everything will become more unambiguous - and there will be a revolution not only in editors, but in everything, version control systems, code formatting, …
Although this requires public awareness, which did not happen, for example, with the EXI XML format.
