I am a seasoned Visual Basic developer on Windows, although I first learnt Basic on my trusty VIC20 & C64 all those years ago, and then dabbled with Hisoft basic on the Amiga (My MUD even started out on that platform...)
Agreeing with most of this thread, I feel that AOS4 should ship with a Basic interpretor editable via a very simple IDE. It doesn't need to compile, and will enable ANY Amiga owner to knock up a tool or app to suit their needs.
I know that if I can't find an app to do what I want, then I can write it myself. Having this sort of freedom really makes computing as fun as it should be.
