A lot of my knowledge in CS come from books and lectures, LLMs can shine in that area by scraping all those sources.
However SO was less about academic knowledge but more about experience sharing. You won't find recipes for complex problems in books, e.g. how to catch what part of my program corrupts memory for variable 'a' in gdb.
LLMs know correct answer to this question because someone shared their experience, including SO.
Are we Ok with stopping this process of sharing from one human to another?
