Writing in the Forbes article, 2020: Animal Advocates Surpass NRA In Political Influence, he speculates about what things might be like in ten years:
Perhaps even more significant has been the change in the legal status of animals, and the way we think about them. That movement began in Europe. Already in 2009 the European Union recognized it was wrong to think of animals merely as "property" and instead gave them a legal status that recognized them for what they are: "sentient beings." That opened the floodgates for court challenges against the confinement and mistreatment of animals.Fingers are crossed.
In the United States the argument focused on our nearest relatives: chimpanzees, bonobos, gorillas and orangutans. Supported by expert evidence that great apes are self-aware, rational beings with close personal relationships and rich emotional lives, courts began to recognize them as having rights, and appointed guardians to protect those rights, in much the same way as they appoint guardians to protect the rights of people with intellectual disabilities. In 2019 the U.S. Supreme court effectively ended research on great apes by requiring consent to each experiment from a guardian concerned with the welfare of each experimental subject. The court left open for further argument the extension of this principle to other animals.
