Your most valuable asset, as an engineer, is not your particular set of skills, however specialized. It is the combination of your skills and experience that put you at a unique position to be able to deliver innovative concepts.
This doesn't just apply to engineers, although engineers are what I have the most experience with. I see the same thing in all facets of a company. A company without innovation is a company that is waiting to be destroyed, which cannot adapt to new situations, and must maintain the status quo and hope for the best. It won't be long until that status quo is disrupted by someone who can innovate, by someone who knows innovation means they can take the undeserved, underserved customers and build something new.
A homogonized culture is the death of a company.
