Cyborgs Man and/or Machine?

I’ve just read an article concerning Haraway’s “Cyborg Manifesto” and it got me thinking. If you think about it, living things and machines are not that different. Take me for example, an average human. Like machines I need a certain type of energy source to function, namely food. If I were to try and process something else, like mulch or something I wouldn’t be able to do much, besides get really sick. Also, like machines I need to move around otherwise I fall apart just as a little used piece of equipment falls into disrepair. However, on the flip side of that I am different from a machine. For one thing, a machine doesn’t care what kind of fuel it uses so long as it’s compatible. I on the other hand dislike strict vegetarian foods even if they are healthy. This comes from a very bad experience concerning a vegetarian pizza. In any case, organic and inorganic, man and machine, just how different are they?
