Ergonomic? Who cares? By 'ergonomic' a notebook it's zillions better than Excel or even Org-mode from Emacs when you don't even have to deal with the limited input from the cells, or worse, localized functions in spreadsheets. Go try debugging some functions in Spanish or German being yourself a native English speaker.

The most ergonomic programming environment in the world today it's a mix between a notebook and a REPL with live changes. Something like a cross between Smalltalk and Jupyter, and that doesn't exist yet. Org-mode for Elisp it's close as it allows you to do literate programming, a REPL and such in a 'live' and documented way.
