I don't consider text a weak medium, but would contend that the strength of the medium is its efficacy in conveying a portrayed concept.

In that sense, text is a strong medium for certain things (like a dataset) and bad for others (like conveying the beauty of a camera pan within a movie that conveys a miniature story).

I've noticed that fanboyism of old AND new technologies is often only grabbing half of the story. We still use "obsolete" technologies, since none of them ever become completely bereft of potential purpose with the development of new technologies, even when they become hipster-niche-chic. Horses or tape storage, for example.
