The top voted answer asks why SO is even trying to improve anything when there's a moderator strike on. What is this, the 1930s? It's a voluntary role, if you don't like it just don't do it.
The second top voted answer says "I was able to do a prompt injection and make it write me sql with an injection bug". So? It also complains that the llm might fix people's bad English, meaning they ask the wrong question, lol.
It seems clear these people started from a belief that ai is always bad, and worked backwards to invent reasons why this specific feature is bad.
It's crazy that you are defending this group all over this HN thread, telling people that toxicity isn't a problem. I've not seen such a bitchy passive aggressive thread in years. Those replies are embarrassing for the SO community, not AI.
What you propose is a complete non-starter.
