I get what you mean, but that's also kind of silly. First, almost no one who is not in the field is going to be even asking it the kind of questions you are. Second, even if they do and try to use that as reasoning etc.. well, then that moron would basically find any type of source (i.e., random youtube video) to prove their "point".
So I honestly think the "harmful" argument is completely out the window. We already opened that pandoras box years ago with basically every piece of human knowledge online in so many places and people making videos on almost everything with all sorts of varying views.
People say this about the coding aspect as well "oh this is going to hurt the world because people will be just asking for code and it will be wrong!" Ok.. but it pretty much sounds like they were just going to do that anyway.
Let's focus on the positives of this infant technology that is still insanely impressive. We are just seeing the beginning, right?
