You’re still missing the point Miyazaki is making. His point is that such a crude depiction of an organism with thoughts and feelings is an insult to actual living thinking beings. The animation might not be alive or sentient, but it still represents a life form that is sentient, and creating such animations that depict sentient beings as incapable as the animation might evoke undesirable feelings in somebody watching that animation, even if they know that it is merely a 2D digital animation composed of bits and pixels that does not have any psychological traits.

I’ve found SimpleX a much better solution than matrix for a discord alternative.
