@cwebber this isn’t really new. For all the things on StackOverflow there was a huge domain of knowledge that was just not on there.
For most of my corporate developer life the knowledge/bug fixes would not be found on public forums but in internal collective knowledge, documentation or simply knowing a person in the same field. Most of this was not public domain.
The biggest issue now is that those firms commit their group knowledge to LLMs and we will not get it back.
