Was this in the 1980s? Because this was commonplace by the mid 90s or so.
Sadly it wasn’t. The medical doctors really did not understand how excel worked. This was around 2015. They did not know it could “do that.”
I took note of who they were so I wouldn’t see them clinically.
I was doing PowerPoint in the mid 90’s at conferences. I think it was the excel functions that blew them away. Maybe it was telling them “the problem” wasn’t their fault probably made them more amazed.
