Although the importance of Google’s search engine has declined in recent years, it remains the world’s most important epistemological tool — the first place many people go to get answers to their questions and fill gaps in their knowledge. Google is now giving precedence in its search results to a chatbot that it knows is unreliable — that it knows spreads lies. That strikes me as being deeply unethical — and a sad testament to how far Google has fallen from its founding ideals.
