Yeah, I think it's the compatibility with 'business language' for collaboration. Most white-collar workers know how to use Excel to a really basic level of proficiency. Not many people know how to parse Python code. It's also just a lot easier to work quickly in Excel. I dual boot Linux and Windows on my laptop so that I can have Windows keyboard shortcuts in Excel. If I need to do some lightweight financial modeling or analysis, it's dramatically faster (10x or more) for me to build a spreadsheet than write some Python/R code from scratch.
