No, different media are different—or, better said, different institutions are different, and different media can support different institutions. Nonfiction books and scientific papers generally only have one person, or at best a dozen or so (with rare exceptions like CERN papers), giving attention to their correctness. Email messages and YouTube videos generally only have one. This limits the expertise that can be brought to bear on them. Books can be corrected in later printings, an advantage not enjoyed by the other three. Email messages and YouTube videos are usually displayed together with replies, but usually comments pointing out errors in YouTube videos get drowned in worthless me-too noise. But popular Wikipedia articles are routinely corrected by hundreds or thousands of people, all of whom must come to a rough consensus on what is true before the paragraph stabilizes. Consequently, although you can easily find errors in Wikipedia, they are much less common in these other media.
