This is a very good point. The Tree Notation ecosystem I work on (https://treenotation.org https://treenotation.org), would only have been an incremental improvement back 30 years ago. But now 1) cruft has accumulated and 2) there are new opportunities to exploit Tree Notation thanks to machine learning (for program synthesis, amongst other things) and visual programming, so the benefits at this time could hit that 10x number.
