Unless a post is prefaced with something like “ChatGpt Says…” I would agree it should not be used a a defacto response. Even then, as my numerous hours of using ChatGPT show, it can give incorrect, or very much less than optimum answers. I am sure one day it will be top notch, but today it is not. Along with the other reasons you cited, it really should just not be used here.
I did a sample basic job interview with ChatGPT to test it out and it failed to get hired. You can read the interview here to see what I mean.
