I would point out that both things are not valid sources, but both can lead you to valid sources with Wikipedia being the generally better option.

You can ask chatgpt to give you academic sources and it will link you, Buuuut it’s a coin flip if they will be real links, or even actually useful. I did find some very good academic sources using chatpgt, but chatgpt is not a search engine, and its results need scrutinized.

Wikipedia will have all of their sources listed at the bottom of the article and those are already human verified.

Still, nothing beats a good old jaunt into an academic database for random finds.
