Just like people don’t like to read books nowadays. Now that everyone’s knowledge is more fragmented, we often choose to read tiktok for a while instead of reading a novel seriously. It's not that people don't like deep knowledge, but compared to it, those fragmented knowledge are easier to accept (because fragmented knowledge does not require brain thinking). I think that although Bitcointalk is more capable of accepting in-depth knowledge than other forums, it is still far from the previous level. Even some dynamic avatars can affect people's concentration, so it's not because we don't want to read in-depth knowledge, but because there is no suitable environment.
