Someone told me an interesting story about UXR from the earliest days of Excel.

They gave the tool to an accountant and watched how they used it.

The user put in all of the numbers in the table… and then got out their pocket calculator to do the sums.

They didn't realize the superpower of computer spreadsheets.

The mental model was "paper spreadsheets, but in the computer."

But by being in the computer, the spreadsheet could be magical and interactive.

A massively more powerful tool than the thing they superficially resembled.
