Thanks for that, Restorer.
(Though I might argue that the white-tipped cane of objective inquiry that is Science and the morally neutral tool that is Technique are increasingly morphed into Magic which not only Dominates, reshapes, retools, manufactures beings and binds men but "changes everything" ... including what we used to call self-evident truth. Science and technology -- in their present forms, anyway -- are not the replacement of white magic but, rather, the Ring.)
Brilliant analogy BUMP.
I suspect Tolkien was fully aware of these issues. Our technology certainly has the potential to dominate us, rather than we using it.
