It's insanely bad. I asked Perplexity: "What are some places named after Alexander Hamilton?" It's answers: Fort Hamilton, Ohio (technically correct, except this is now known as simply Hamilton, not Fort Hamilton); Hamilton, Ontaria; Hamilton, NZ; Hamilton, NSW. None of those last three are correct.

I asked Google the same question and it has the Wikipedia page "List of things named after Alexander Hamilton" as the top organic result, with nothing ranked above it (ads included). It also offered an AI summary that isn't totally, flagrantly incorrect, listing Hamilton Place, Hamilton Hall, and Hamilton Heights in New York.

People who write these articles about search quality are blinded by some unstated ideology.
