> SO was by far the leading source of high quality answers to technical questions

We will arrive on most answers by talking to an LLM. Many of us have an idea about we want. We relied on SO for some details/quirks/gotchas.

Example of a common SO question: how to do x in a library or language or platform? Maybe post on the Github for that lib. Or forums.. there are quirky systems like Salesforce or Workday which have robust forums. Where the forums are still much more effective than LLMs.
