Personally, I like that as a human, I have the capacity to use tools as an extension of my being to improve myself and my place in the world.
I don't think applying the same tools I use to solve problems in the physical world to solve problems in my mind makes me any less human. Sure, those tools may not be a perfect match for the problem domain and provide the wrong answers sometimes, but it doesn't hurt to try applying them.
I don't think this makes me a cyborg any more than lighting a fire or driving a car does.
