Learning and Developing AppleScripts

Just coming across articles about scripting languages being depreciated over the next couple of years:


What does this mean in relationship to my nascent AppleScript ambitions? Would it be a better long-term plan to focus on Swift or elsewhere?

I gleaned that with additional work things will continue as before for a couple of years and reading the tea leaves is always tricky, still, this seems be suggesting a significant change in the making.

I don't yet understand the larger structure that scripting fits within and so can't fully appreciate what these articles are saying. If anyone would translate into a CliffsNotes-ish conversation for us neophytes I'd appreciate and maybe understand a little more.
