Is mathematics becoming more applied, while engineering is becoming more math-y?

I’m seeing curriculum changes at our school that has pretty good math, physics, and engineering departments, and it seems that the vision is that soon math majors will be taking courses in both the mathematics and engineering departments. And likewise, it seems that some engineering research will be done collaboratively with mathematicians. So I’m wondering if this is a general trend that is happening, at least for universities in the U.S.

Are there any references that support or oppose this trend? For example:

- Bibliometric studies.
- Publications of professional societies.
- Official statements by departments, faculties, or universities.
