I could have sworn that I heard/read that the original intention behind the jockey in the chair was that they were a species that grew so dependent on their technology that they eventually evolved to become part of it.
I can't find where I heard this. Might have been on the blu-ray somewhere. Can anyone confirm this?
Before Prometheus, I ran with this and imagined every jockey being physically built into their jobs in sprawling Giger-esque cities.
