Stack Overflow has been less useful for several years before OpenAI.

I find for web technologies it's less useful because the technologies keep change, and what was a good answer in 2010 is not now. To answer questions I find it more useful to consult a primary source, such as the documentation on a some software's website, or a forum dedicated to that software.

On SO I often get no replies, or unhelpful and often toxic comments along the lines of "Technology X is bad, use Y instead".

Or I often get people who answer the question as if they show applying for a job at Google. No, I just need help with some software to process a few thousand rows and send a summary once a month by email. I'm not trying to process petabytes of data with a response time of <1ms.
