You don't have to be an "expert in AI". What does it require to be one, anyway? (He's a cognitive psychologist, which would make him an expert in intelligence in general, if you want to be pompous about it.) It is even unreasonable to listen to only experts in AI. It's a problem that requires more than one perspective.
Would a clinical psychologist like Jordan Peterson be equitable or are these two distinct fields in the realm of psychology? (I am not well-read into what he thinks about AI).
Clinical psychology is mainly concerned with diagnosing and treating people's psychological problems. The clinical psychologists I know don't know much about AI, but might be able to research problems stemming from its use.
