>>3146267>zaShunina was doing the same exact thing, except his choice involved the death of like 99% of humanity.
I have to disagree. I have watched the last episodes several times (from streaming it for friends and because I write fic), and nowhere is it explicitly stated that zaShunina's plan would have killed humans.
(I can only remember one line of zaShunina's where he agrees that perhaps not all of humanity could ascend - but he planned to test it with Shindo first, and his gifts were meant to ensure success; imo it is not in the anisotropic interest to kill humans, generally - less humans = less information)
Even Tsukai's opposition is not based on this - her opposition is to elevating humanity and giving them eternal life, thereby ruining humanity's ephemeral nature, and making them less "human", in her opinion.
If danger to humanity were the reason for opposing zaShunina's advancements, then it should have been more explicitly shown and stated in canon, but it's not. zaShunina's gifts DID have the potential to cause untold harm (the Nanomis-hein, especially), but the risks are merely stated in expository dialogue (or not at all), the danger never shown, other than some people getting seasick from the Sansa. Even the people who were sucked into Kado showed no sign of physical harm (Shindo's mom was shown to be perfectly fine).
Good storytelling is "show, don't tell". If they wanted to portray anisotoron interference as truly harmful to human lives, then they would have portrayed it as such, showing the ill effects from zaShunina's gifts gradually, as the show went on, triggering chaos in human society. Instead, all we are shown are their positive effects.
This was not a life-or-death conflict, but a conflict of ideas.
I also think that it would have been far better for Shindo to negotiate with zaShunina, and come to an agreement that would allow humanity to choose their own path - a goal that was brought up repeatedly in the earlier episodes.
