A Software Engineering Homunculus

A cortical homunculus is a graphical representation showing how much of the brain is devoted to different parts of the body:

It would be fascinating to see a similar diagram showing how much software engineering research effort is devoted to which parts of the things software developers actually do. I strongly suspect, for example, that the ratio of research to practice is much greater than unity for software product families, while there is much (much) less research into installation and package management than there is practical wrangling. If someone has a grad student looking for a project, I'd be happy to chat…
