I've used it to search some techniques on simulations as all it does is link me to some developer pages saving me a few minutes here and there to find the exact phrasing. But that's a rare field and hasn't been inundated with snake oil.
Would never trust it to diagnose a human condition or do my taxes nor trust the links it sent me to. So many hawkers with our without ai around that topic
So yeah, I think they should take some culpability on that and maybe they'd be forced to clean up their search engine as a result.
