While I agree that text might not be the best way to represent a program, text files have many convenient properties that make them hard to replace:

- Simplicity: every computer and most humans can interptet it without any issues

- Diffing: it's relatively easy to tell what changed in a text file between revisions

- Editing tools: text editors, formatters, etc. exist and many people know how to use them efficiently

Also, modern developer setups allow you to manipulate code as a syntax tree (see tree-sitter text-objects) and intellisense and snipping tools allow you to type much less.
