I am not in that universe, on the contrary I try to stay as far away as possible. And I agree with you. However I think the everything-done-in-OLD-Excel universe is worse. Some people will be terminally stuck in Excel but at least they can use new Excel capabilities instead of being stuck with the Excel of 20 years ago.
So why remain stuck importing CSVs into Excel when you can use Power Query to import Parquet. Why remain stuck using VBA in Excel when you can use Python in Excel.
I do not think an Excel user can be convinced to move to things like Jupyter, R, databases, etc. since they won't even make the jump to Access but maybe they can be convinced to use modern features of Excel.
