This would be a huge disservice to patients with neurological diseases. Speaking from my little corner of science, the remarkable recent progress in brain-computer interfaces to restore lost abilities (like speaking, moving, walking) were made possible by NHP studies!
Let’s just say I have my sources. I don’t necessarily think they’re going to stop it, but it’s extremely expensive and that makes it a candidate for the chopping block. Also, it’s controversial. The new trend elsewhere has been to maintain primates out of country where risk of infections is lower and cost of doing research is far lower as well. I know, researchers that maintain their mice in Singapore for a tiny fraction of the cost and then ship them in for experiments. Again at a fraction of the cost to maintain them at universities here. But not everyone can do that. Depends on the work you’re doing.
