I think all that only makes phones a communications tool, not religious, nor idolatry.

People have been moralising, preaching, dogmatists in the Letters to the Editor since whenever "Disgusted of Tunbridge Wells" was coined — I don't think that's enough to have made The Daily Mail or The Sunday Times into an idol, nor the newspaper preference into a denomination (even if there's that quote from Yes Minister).

But we are busy making Golems and Húsvættir, and you are right that superstition still plagues us.
