I’ve witnessed only a tiny number of noteworthy moments in #tech, but as a summer intern in 1987 I attended MacWorld and was in the auditorium when Bill Atkinson introduced #HyperCard. Completely mind-blowing: graphics, simplicity, expressiveness.
I remember HyperTalk’s surprising use of `it` as an accumulator:
```
get the selection
put it into the message box
```
I can’t name a contemporary user-friendly #programming environment that lets you create apps/sites as easily as HyperCard did. ☹️
