Yes, I would agree there is significant effort required to
become proficient with Mathematica and there are other languages
that are easier to learn.

Yes, that was the gist of the original question. And Lisp might
be easier to learn. But Mathematica isn't Lisp. Possibly
learning Lisp first might make it easier to learn Mathematica.
Another real possibility learning LIsp would make it more
difficult to learn Mathematica. Expecting Mathematica to behave
like Lisp could cause quite a bit of problem which would be
avoided if you didn't have a Lisp background.

Possibly Mathematica is harder than necessary to learn. I don't
have any real way to evaluate whether that is true or not.

I agree Mathematica is different in a great many ways. And I can
see how someone experienced in say C or another language would
see Mathematica as strange and unusual. But I really don't see
the problem of understanding Mathematica symbols, precedence
etc. as being any different than learning pointers are other
aspects of C. It is simply a matter of study and using
Mathematica just as it is a case of study and using C to learn
pointers etc.
