Fact updated: In recent days, China is encouraging young people to have more children, in order to fight population aging. It is now allowed to have 3 children per family. Despite the recent propaganda of having more children, lots of young people in China are not willing to have even one child because the higher education and/or marriage cost, and the birth rate keeps dropping.

IMO if AGI goes well for humans then at least it would have a decent grasp for general ethics, which includes animal welfare. AGI that hasn't got good ethics wouldn't benefit human, they'd just paperclip around. Since I have a short-ish timeline, i think somewhat-ethical and empowered AGI will benefit animals more than speciest HGIs.
