My point is mostly that it that Jupyter far from as bad as spreadsheets (at least commonly used implementations).

Correctness of machine learning is a complicated problem generally.

Meh. With some of the practices I've already seen, at least spreadsheets always show the data. You send me a spreadsheet, I can verify most of it. Send me a notebook, I can typically only audit what you did.
