More as an alternative to a search engine.
In my ideal world, StackOverflow would be a public good with a lot of funding and no ads/sponsorship.
Since that’s not the case, and everything is hopelessly polluted with ads and SEO, LLMs are momentarily a useful tool for getting results. Their info might be only 3/4 correct, but my search results are also trash. Who knows what people will do in a year when the LLMs have been eating each others slop and are also being stuffed with ads by their owners.
