Unfortunately human control does not help Google's bottom line so it's not going to happen. Google must always place lucrative ads in front of people using search. That will always be a conflict.
I think if someone came up with a decent search engine for research that used operators to filter results it could be a big success. Google has proven conclusively that with the best will in the world search that is totally dependent on profit does not work well for the user.
