Where do you expect them to pull the information from? The entire internet is filled with wokeness and all the repositories a search engine would draw from are tilted towards the marxist rewriting of history.

You'd have to design a search engine that was equally biased in the opposite direction to actually get decent results. Or just filter out all results less than five years old.

Or, people have to actually start talking about something other than black inventors again to get the results you want. Since the artificial dialogue is only about black inventors, that's what any search algorithm would return. No matter who wrote it.

No one is writing a "great American inventors" article in the current decade that doesn't try to erase white men, so that's the kind of information we have to dig through. Until someone designs a search engine to detect and then ignore wokeness, this is a problem much, much bigger than biased search algorithms.
