One, it doesn’t seem like they’re comparable products for most uses.
ChatGPT, the user-facing website, is not comparable to google, but the technology itself is directly comparable. I am using Google's own brand of chatbot-in-search (not bard, but probably is bard in the background) and it really does a good job taking the information from the top couple search results and compiling it together in one place for me to get the answer to my question. It seems (seems) less likely to hallucinate since it seems to be pulling information specifically from the search results; I obviously don't accept what it outputs without clicking through to the source websites, but I could see that becoming unnecessary in the future, since so far I haven't seen anything misrepresented or made up.
It's like Google's thing where they pull short answers to questions from popular websites (like wikipedia) but dialed to 11.
