A non-human person is a corporation, not an orangutan.
I would find this latest overreach of corporate law amusing, if it wasn’t so horrifying.
Larry Niven had a number of short stories where dolphins were legal equals to humans. The big difference between that fictional universe and this one was that dolphins could communicate via machines, make contracts, discuss topics. Via the communication route, they were deemed as intelligent as humans and thus killing one was murder of a non-human sentient. The dolphins reciprocated by working on ocean farms for “hands” and help they paid for.
The orangutan cannot do any of that beyond ask for more food or sweets via sign language. It cannot communicate advanced concepts. It isn’t an intellectual equal - it is only raised to human legal status by people who want to lower the ethical standard of animals.
