AppleScript was originally conceived to be easy enough for non-professional programmers to read and write, with the history of Hypercard behind it. This is for those rare occasions when they needed to
automate something that they do with multiple applications manually. At one point, you were able to hit "Record", do the things that you needed to be automated and boom you get a script that you can begin to massage into something reusable. You didn't need to be a programmer to read this recorded script and you didn't need to know English to read/write it either (it was available in other languages). It looks like Apple realized that
automation is the core problem they need to solve and made .. Automator instead, which is based on the same underlying piping - OSA.
edit: Back in 1998/99, I even wrote a web server entirely in AppleScript - it was a platform for our research lab to share, debate and record ideas.
