SSE remains relevant (and World of Motion would have remained relevant) because it's (their) primary focus on is/was the history and evolution of a technology with only a mere, somewhat vague glimpse into the future. Like Carousel of Progress, this approach prevented it (them) from becoming dated and thus made it (them) relatively timeless. Only the final scene(s) need(ed) refreshed every decade or so to stay current as opposed to the entire experience.
Exactly my point. I forgot to mention World of Motion along with Spaceship Earth, but as you said, it falls under the same umbrella, although not quite to the same extent as SSE.
