I find it useful in a lot of ways. I think people try to over apply it though. For example, as a software engineer, I would absolutely not trust AI to write an entire app. However, it's really good at generating "grunt work" code. API requests, unit tests, etc. Things that are well trodden, but change depending on the context.

I also find they're pretty good at explaining and summarizing information. The chat interface is especially useful in this regard because I can ask follow up questions to drill down into something I don't quite understand. Something that wouldn't be possible with a Wikipedia article, for example. For important information, you should obviously check other sources, but you should do that regardless of whether the writer is a human or machine.

Basically, it's good at that it's for: taking a massive compendium of existing information and applying it to the context you give it. It's not a problem solving engine or an artificial being.
