We used to teach little children to use OpenScad years ago along with programming(I volunteered for that). Kids learn fast.

Now we teach them FreeCAD, and python scripting for the advanced ones.

I have no idea what the author is talking about, designing a 3d editor is not trivial, most kids don't need very advanced 3D editing either. They will just ask the one who is good at it, or download it from the Internet from already made models.

There is a need for 3D curves in the Open source world. This will be worked on over time.
