I didn't intend to denigrate your work - I think it's really interesting.

However, to advertise it as not being programming seems bogus to me. In Excel, you click the "fx" button and choose "SUM" and then select some cells with your mouse and it pops in there =SUM(A1:A4) for you, which feels in practice quite far from what I would consider programming, and I think people who are non-programmers but have the right sort of mindset can usually fathom this stuff.

The example I quoted above, however, looks a lot more like programming to me, and the nested parentheses alone would be enough to scare off a lot of non-technical types. I have dealt with many people over the years who have to do a bit of programming in their roles but really aren't programmers in the conventional sense, and they find things like the difference between A(B(1,2,3)) and A(B(1,2),3) extremely hard to grasp.
