But as a programmer, I still use excel (actually open office now I'm on Linux full time) as a brainstorming numbers based scratch pad. Somthing about the infinite grid, auto fill, not having to figure out all the parts of a 2D array allow me to chase an idea in its initial stages.
Eventually, when I have a handle on the problem and all the variables involved I will switch to jupyter notebooks or something else.
I still think we as an industry are still missing the point of why are so many people using excel, especially in areas it shouldn't be used in. There is some hidden UI/UX point we're subtlely missing.
