I just watched the video in question, and this is an entirely backwards take. Miyazaki is saying the animation is an insult to the pain of those with disablities like his friend, not disparaging people with disabilities.
It isn't specifically about generative ai, but he is talking about art (animations) made through machine-learning being a cold mimicry of real human efforts. I think the comparison is pretty fair and it applies in both instances.
Der Tagesspiegel is not a good source for anything remotely based in reality regarding Palestine or Israel. The newspaper is owned by the Holtzbrinck Publishing Group, which was founded by an actual nazi (not hyperbole), and it's still run by his sons, who are some of the richest men in the world.
The editor in chief, Stephan Andreas Cassdorff, has also written articles for partisan pro-israeli organizations which are full throated in their support of the IDF.
If you can find another source for any of that, please do.
