For good or bad, big companies run on Excel.

At my last job - a large tech company - if it wasn't in Excel, then engineers and HR wouldn't use it. The team had a tool that collected data from various databases for the end user and did some analytics. The code was in Python. The output was an Excel file.

I asked why they didn't use pandas.

"Because the users are just going to take the output and put it in Excel."

It was a very successful tool. No one needed to use it so we had to ensure users liked it. All due to the team lead's wisdom on how big companies operate.

They also wanted us to autogenerated PowerPoint files. We gave up on that. The spec is a mess.

I used to work as a trader for a major investment bank. Everything was excel. I can’t see it staying that way.

You now have that app forever and nothing connects it to Claude other than the comment saying "this isn't just rounding — it's the single source of truth for the shared ledger boundary, not a formatting concern."

While I agree that spreadsheets are likely to be used less by regular folk, the idea that we'll become reliant on claude feels unlikely.
