The problem with ChatGPT as a replacement for Google is that it was not designed to produce accurate facts, and it shows. This model cut its teeth writing articles about the discovery of unicorns in the Andes[0] for goodness sake! It's a language model, and a very impressive one at that, but language is used to express falsehoods and fiction just as regularly as it is used to express truth. This doesn't mean that it…
ChatGPT in its current form can't replace google but plausible to think in its next few incarnations it will get there. Why can't it have a mode where it returns more rigorous results, and includes some system of links as citation? It can include footnotes for various passages of it's answer to indicate ambiguity, varying levels of confidence, etc.
There's also the ethical question. For example, duckduckgo will show you stack overflow answers. Google could easily do this but they have already gotten flack for displaying answers and taking away clicks from sites, which means reduced ad revenue for the resource actually being used. We could make even stronger arguments about services like ChatGPT in their current form, let alone the one we're talking about.
If we think a bit further in the future there's another extension that might not be what we want. Suppose our model contains all current human knowledge and can accurately give you answers and even produce paragraphs at will. This kills off a lot of websites. Is this a good thing? Suppose we incorporate an image generator along similar lines and now we have text and image search. That's a huge centralization force. There are a lot of great benefits to this that I don't want to downplay, but we should also think about if this is actually what we want because there are downsides too.
I thought I should also add that I had an at length discussion of these LLMs being Stochastic Parrots (an how we know they are) in a thread from 2 days ago https://news.ycombinator.com/item?id=34113011
