Again - to each their own. But what people use google for GPT doesn’t replicate anyway (and what the Google business was built on) - which is commercial info retrieval.
For the majority of my use of ChatGPT and Google, I need to be able to get useful answers to vague questions - answers that I can confirm for myself through other means - and I need to iterate on those questions to hone in on the problem at hand. ChatGPT is undoubtedly superior to Google in that regard.
Google search reminds me of Amazon reviews. Years ago, basically trustworthy, very helpful. Now ... take them with a tablespoon of salt and another of MSG.
And this is separate from the time-efficiency issue: "how quickly can I answer my complex question which requires several logical joins?", which is where ChatGPT really shines.
And for my single query above, ChatGPT searched multiple sources, aggregated the results, and offered a summary and recommendations, which is a lot more than Google would have done.
ChatGPT's major current limitation is that it just refuses to answer certain questions [what is the email address for person.name?] or gets very woke with some other answers.
