ChatGPT is like gambling, even though with slightly better odds. It can suggest complete nonsense with seemingly great confidence.

If you have true experience in some field try to ask ChatGPT some questions and you will be shocked what nonsense it suggests, put in very nice words.

From a random blog post that a search machine brings up you can often get some clues whether the author has good understanding or just wrote down a random finding they had during trial and error. And that finding is still more on the side of error than doing it correctly.

In ChatGPT answers I don't see such hints.

You can further gauge the accuracy of a blog post if the author included links to sources. ChatGPT doesn't bother with sources because it can't trace any statement it makes to a source.

It will actively invent fake sources. Ask it to write a Wikipedia article with references and it makes up fake ones that sound like real things.
