I would've agreed in 96 (wow, sounds so long ago now!).
But then when I think about what was left even six months ago: the architecture (next to WoM perhaps the best architectural expression of its pavilion's subject matter), the ride system, the dinosaur show scene, the preshow area and two theaters.
The Radok blocks, lasers, mirrors were gone, but a 21st century show could be installed in their place. Energy Exchange was gone too, but the CC structure was still right there, including an entrance directly across.
Energy could've been saved, in 2017. If we would be an era where Disney does not define itself by its franchises but by quality theme park design then a great Energy update was still possible.
Although new updates always woud've left the pavilion slightly less off. The architecture expresses 1982 forms (the beginning of the CAD era and it shows, a deliberate contrast to the square blocks of the age as a statement, etc), the Radok blocks are 82 technology, with 82 aesthetics, the dinos are represented in an 82 setting (a dark and mysterious world...smelling of volcanos and lava...sluggish reptilian dinosaurs leading a life of brutal primeval drama...), all in an 82 intellectual environment of space age modernism, of people marching towards a great future. There is an overwhelming unity of form, music, content, purpose. You can update a few elements, but the downside is always a decrease of unity.
