As for me, ChatGPT and Claude were able to diagnose and fix health issues that multiple doctors failed to fix. I trust LLMs more than random doctors and blogs. Cause they are able to search the web deeply, search for up to date info/research and synergize all that. You can have back and fourth for as long as you need. The issue is that using LLMs properly requires a certain skill that more people lack.
And I don't mean I've just rejected the lowest offer to DIY shit to oblivion. I've accepted bids and been continuously disappointed with the results. To the point I no longer trust "experts" in these spaces because any "expertise" they bring is pretty shallow at best. The exception I'd point out is the auto-shop I prefer. They are busy enough that if I want to schedule something it's going to be 3-6 months out. As a result I've replaced my own suspension and replaced my alternator and starter myself while waiting for appointments with the rare actual experts in any domain. Actual expertise is rare and most folks don't know how to recognize it, especially outside of domains they are familiar with. Unfortunately it's way more profitable to fake expertise in various domains and collect payments and run than to actually stand behind your business and work. Thus the world we're forced to live in today.
