Any form of curation, whether human or automated, will have biases and opinions. For example, historical encyclopedias were strongly in favor of the status quo. Even Wikipedia, which does a much better job, still has quirks and biases:

- the source reputability criteria prevents much of popular knowledge/culture to be referenced (police abuse example: first-hand witnesses are not considered reliable sources unless quoted by a big newspaper)

- the topic reputability criteria prevents many interesting figures from being referenced (see previous HN discussions about why women scientists are mostly absent from Wikipedia)

Neutrality is a lie. Everything is subjective. We can try to provide broader interpretation and critique, but no single entity can cover every aspect and worldview. In my view, that's a feature and not a bug.
