I think I commented at the time that I was a little surprised we only took one step forward in technology. For as advanced as this Crystal Seminar is supposed to be, any programs should really have been available digitally, or at least on a thumb drive. That lacks both visual appeal and (if digital) Usagi just stumbling on it later though, so I get why we didn’t upgrade higher than a CD or DVD for the story in this form.
Still, it hammers home how this plot point just really doesn’t age well. Back in 1992, computers were still extremely advanced things, only beginning to make their way into homes and classrooms. Jadeite’s cram school using them was a sign of how advanced it was, so made sense without a lot of extra work on the part of the story why a genius like Ami would go there. These days, however, a mass computer presence would be a minimum expectation. The use of optical media actually makes it look DATED.
I find that fascinating from a creative standpoint, particularly with the use of technology as shorthand. Given enough time, technology will always date a story. This episode’s strict adherence to past story elements, however, highlights how, for a reboot to be as effective as possible, sometimes entire plot points need to be gutted and reworked.
In funnier news, while I know it’s simply a language-based misspelling, if we consider that whole setup involves Jadeite in any way, then I’m dying at how he can’t spell his own creation.
