Excel is by far the most successful programming language and IDE. People love to hate it (and the people using it), which is somewhat misguided: there is simply no way to change people (and they keep making new ones), so telling them that what works for them is somehow wrong is both wrong and doesn't work. Instead, the spreadsheet paradigm has the promise of being far more powerful. Jupyter notebooks are one example of adapting it to a different realm, and it also ended up being used everywhere and looked down upon by the snobs.
