That was a neat detour into reinsurance. I wonder how the main thrust of the article holds up generally. My experience in trading/finance is that Excel remains extremely preferred for last-mile use (i.e. for writing and reading reports). Whereas the data science ecosystem has been adopted to develop research platforms and manage the data into (what ultimately becomes, for most users in the organization) an Excel sheet. I don't see this changing any time soon. I think Excel was always strongest for last-mile use. Excel is extremely powerful when you know how to use it correctly, and I routinely see people match or exceed the productivity of programmers using it for specialized use cases.
