You have to have some idea as to what the answer might already be
it doesnt provide sources etc. which is a bit annoying.
the chatgpt "bot" in the edge browser is actually decent at providing sources, but its terrible at finding specific info. i tried finding information about what TIME a certain game would be available to play, and it just kept giving me its release date. (which i also gave it, in my query)
but they're still very new.
google, and such, have had over 2 decades to refine their search etc. and to be honest i think the issue is its not giving you "generic" results. its trying to specify the results based on your previous searches etc. which means it can be difficult to find new info...
as for chatgpt ..
i use chatgpt quite often to summarize a large blob of text, in a simple manner, or give me code snippets for generic stuff im too lazy to write. test-data as well. or just "facts" about some topic. simple stuff.
chatgpt works by looking at your query, and then based on that, it tries to find the queries "key words" and fetches some result based on that. It only gives you one result. and as we've all tried when searching the internet, often times the list of results will show stuff that is clearly not what we're looking for.
