10 years ago I joined a consulting company as a data science intern. I arrived at work with my MacBook. I learned about excel in courses but had never used in my daily life: I use csv and SQLite for "data-heavy" cases and Numbers for intuitive cases (never coded inside it). When someone shares an excel sheet with me, I open with Numbers with no problem.

On day 1 I realized my work was to deal with several excel sheets of 10~50MB, with huge amount of VBA scripts, rule-based highlighting, charts... They even wrote an internally used extension for those files. Numbers could not handle and crashed.

I need Excel. I asked if I could borrow a PC laptop from the company, no, that's not for interns. I need to bring my own device. I asked if they would pay for Microsoft Office to get installed on my personal MacBook. The answer was obvious, what are you thinking? I had to manage to get Excel for myself, while the full salary they paid me was not enough to cover a license.

I left consulting after that experience and end up working as a "real" data scientist. Nothing like that happened ever. I collaborate with colleagues using different IDEs/editors everyday. If an accountant joins us and tells me notepad is all you need, I would highly respect his choice and continue with my editor. We don't need to argue, our codebase is not locked in any tools.
