Read Holly Ordway's book, 'Tolkien's Modern Reading', and consider that Tolkien's 'disdain' for the changes wrought upon the world for the sake of progress, has been considerably exaggerated.
Ordway believes that this exaggeration is primarily due to two causes, the Humphrey Carpenter biography of JRRT (and his book on the Inklings, and his selection and editing of JRRT's letters) all of which she thinks were slapdash, unscholarly, and prejudiced, and the conflation of JRRT with C. S. Lewis, Who was much more anti- modern than JRRT. Lewis used a dip pen all his life. JRRT was an early adopter of the Biro ('ball point pen' to Americans). Lewis never learned to type. JRRT owned multiple typewriters and typed much of his work. Lewis disliked automobiles, and never learned to drive. JRRT reported of automobiles that he, "loved riding in them, liked driving them". He owned one as early as 1932, and later bought one for one of his children. JRRT also loved Science Fiction, and read it extensively.
So, yes, JRRT disliked some modernizations (after all, he witnessed two great and destructive industrialized wars, in which technology added to the mayhem and devastation). But the concept that he was totally conservative, a luddite, and opposed to technological and scientific progress is greatly exaggerated.
So, yes, JRRT may have felt some kinship with the desire of the Elves to preserve all things. But this aspect of his character has been blown out of all proportion, and might not be so prominent as popular understanding believes?
