I agree with those saying it's not AI, but it isn't ideal.
It works okay for things where you might need a same day appointment- i.e. you get a phone call back, arrange an appointment, all good.
If you need an appointment but are at work, it's very tricky- I can't always answer the phone at work, and my signal at work is also very poor. If you don't answer, or get cut off, there's no option to say "can you please call back in 2 minutes when I'm in a private room/somewhere with signal etc". I fully accept they can't hang around forever, but it does make it difficult to access healthcare.
I'm also not sure how it works in terms of routine appointments etc. I'm supposed to have a medication review at some point soon, for a new medication I've started- I couldn't book an appointment whilst at the surgery, and there doesn't seem to be a good option for this on the form, either...
Overall, I do think it's probably better than the "call at 8am" system if you're acutely unwell and need help there and then, but for more routine stuff it's not as good as speaking to a person?
