I once saw a supervisor use Google sheets to do a simple calculation. Could have opened the windows calculator, could have typed it into Google, could have done lots of things. But no, they created a new Google Sheet, performed one arithmetic equation, and then closed the browser.

I was so amused by this that I decided to program a 10-key calculator complete with memory recall in Google Sheets using Google Apps Script. I've made some wild Sheets over the years and have abused spreadsheets into things they're not, but that's my favorite, most useless Sheet ever. Whenever I show it to people, their first reaction is, "yeah, that's a calculator, that's a pretty simple tool." But then when they realize that I wrote actual code to assign values to add then clear checkboxes and then store all these values, they look at me with genuine concern.

I know this isn't the kind of delusional you're talking about, but just wanted to share.
