HN demonstrated its common ability to surface prolific posters who identify as autodidacts and appear to have gone on a Wikipedia binge this morning, but who nonetheless speak with a confidence that until now may only have been demonstrated by ChatGPT.
The absolute worst part is that some of these guys, especially the younger (e.g. fresh grad through ~30) ones, do this in person! I was out drinking with some colleagues a few months ago and I said something offhand in a normal human conversation about wanting to learn more about X, and one guy pulls out his phone and just starts reading me the Wikipedia article about X.
I could personally take or leave live readings of Wikipedia. I wouldn't do it, but I have also gone on my share of solo wiki binges. There's no problem with learning about things. The thing that bothers me is a room full of people with shallow knowledge of a subject who talk over anybody else. I think it's fine to care about things, but I need other people to be able to tune their volume to their level of knowledge and understanding, which you really can't do if you think you know everything.
