It speaks to both the genius that exists within the design of the spreadsheet digital document format, the effectiveness of excel's implementation (and microsoft's business), and the dismal state of IT empowerment and education that there is nothing you could show me implemented on an excel spreadsheet in a business that would surprise me.

It goes from the obvious stuff like DBs to Hypercard clones to really far out stuff when you get to shared documents.

Excel gets so much wrong but having sampled some of the competition and being proficient in programming at this point of my life I can only admire it and people who go deep.
