HN has a huge user base. If the article is pro-AI, you'll see top comments praising AI. If the article is anti-AI, you'll see top comments deriding AI. The article and headline is just an attractor to those whose opinion is aligned. It's not unique to AI, basically every thread has your typical nerd-fights, but AI has been particularly polarizing for many reasons.
