This is complete bs, real innovation happens exclusively in the top 1 percent of the field. This is just coolaid that some people like to drink to de emphasize the value of real skill and inflate their own egos.
Real innovation in art software for example could only be done by someone who is highly skilled and experienced in both artistry and software engineering and has an very open mind when it comes to design.
You get get things like Sonic Pi from people who are both musicians and developers.
