As a programmer, you're probably a lot better at understanding what a search is/does and how to pick good keywords or which keywords you can swap and refine to get better results. Most of the general population isn't there in my opinion (just based on what I've seen around other people trying to search thing). The general population doesn't use site: to restrict results, - to remove a word or even " to search for an exact phrase.

I think those are the people who could benefit more from a more context-knowledgeable search, and I think that's still a huge majority of people.
