It depends on where you live and what the issue is.
Where I live, doctors are only good for life threatening stuff - the things you probably wouldn't be asking ChatGPT anyway. But for general health, you either:
1. Have to book in advance, wait, and during the visit doctor just says that it's not a big deal, because they really don't have time or capacity for this.
2. You go private, doctor goes on a wild hunt with you, you spend a ton of time and money, and then 3 months later you get the answer ChatGPT could have told you in a few minuites for $20/mo (and probably with better backed, more recent research).
If anything, the only time ChatGPT answers wrong on health related matters is when it tries to be careful and omits details because "be advised, I'm not a doctor, I can't give you this information" bullshit.
