I have to disagree with your assessment of notebooks. I use them mostly for exploratory data analysis. It’s great for being able to view multiple graphs at the same time, tweak some parameters and see what changes. Then of course being able to easily share your findings. I agree as a development environment it has a lot of drawbacks. Hard to debug and global variables galore. I don’t view them as an end to end solution but as one step in the workflow
Don't forget also documenting your findings. Without a notebook, results end up divorced from code stuffed into a folder with weird names. To properly document you have to write something in latex or word or markdown, but with a notebook you can keep code, graphs, and notes all together.
