I really hope to see the end of research on captive primates in my lifetime. While many countries have banned the practice or imposed heavy restrictions, there are still many apes and chimpanzees who haven't yet been "retired" to sanctuaries.
It's happening, but not as quickly as we might hope.
Even many people who aren't against animal research in general see the use of primates as different. They're close enough to humans to make the issues far more apparent.
