A bad chatbot would be bad, but a good one can be better than good docs because it can give an answer that's tailored to the details of your question.

For both docs and chatbots, quality is just a question of how much the company is willing to invest.

However you want to take this... but we'll have good bots long before even a fraction of help docs are good on this planet. Good docs are as rare as diamonds.

Several times I've found help from a regular FAQ though. That's something yet to happen with a support "AI" bots. I sure hope we'll get there soon, because right now they still seem to struggle with mixed case, exact-word queries
