Personally this a great feature for me.
In my mind, AI for search is one where there's an attempt to answer (with source to back that answer) and also provide an efficient list of relevant links to other sites that it believes is related or part of what I was searching for. There's nothing really 'hidden' more so than before in my opinion.
The test for AI is will users find results better and faster than before. Which so far seems to be yes as far as I am aware.
However I understand where you are coming from with the Chat-GPT interface just spitting out a result and completely obviscating where it came from.
