With Gemini you can let it show you search results for (some) of its statements. It's useful for cross-checking: I was, for example, researching plastics recycling and there was a claim that seemed untrue and corporate. The automagic search/source function for that statement led me to a blog post of some consortium/lobbying group
of manufacturers. After telling that to Gemini it apologized and compiled a list of different view points for that specific statement.
I was pretty impressed with that, and I find it very useful for researching topics I know basically nothing about. Of course it's not the sole source of truth.
