Hm... This is not the place for talking about this, but I've always been more interested in the artistic side of figure skating than rotated jumps, correct edge take-off, etc. I don't care as much about AI in judging as the return of aesthetics, skating and programs. Historically, it's been fluctuating between technicalities and artistry. In the 70-80s, the artistic skating seemed to be on the rise, and we are still seeing the result of this in choreography from Sandra Bezic and Lori Nichol who I believe skated in John Curry's show, and their students. Then figures were gone and by the 2000s, quads in men, triple-triples in women became a necessity, but late 2000s-early 2010s brought back artistry, programs and an advance in skating skills. Now it's jumps again, so I hope for another renaissance. Perhaps, if one had more data from earlier years, similar tendencies could be traced, but there is really not enough. I agree that archiving rules and results and removing videos from youtube doesn't help. You'd be hard-pressed to figure out e.g. how spins, steps and spirals were given levels circa 2010 OG, and this was only 15 years ago.
