I'm excited to see what national disasters will be caused by auto-generated Excel sheets that nobody on the planet understands. A few selections from past HN threads to prime your imagination:
Thousands of unreported COVID cases: https://news.ycombinator.com/item?id=24689247
Thousands of errors in genetics research papers: https://news.ycombinator.com/item?id=41540950
Wrong winner announced in national election: https://news.ycombinator.com/item?id=36197280
Countries across the world implement counter-productive economic austerity programs: https://en.wikipedia.org/wiki/Growth_in_a_Time_of_Debt#Metho...
Especially combined with the dynamic array formulas that have recently been added (LET, LAMBDA etc). You can have much more going on within each cell now. Think whole temporary data structures. The "evaluate formula" dialog doesn't quite cut it anymore for debugging.
