Chatbots: more trouble than they are worth?

We recently did a Show HN post that unexpectedly got to the front page and drove a tonne to traffic to our site.

We use an Intercom chatbot to qualify leads, basically asking some simple questions e.g. "Contact sales"

One of the most consistent pieces of feedback we got was people hated the chatbot. Not "here's how to do it better" just straight "ditch it entirely".

So are chatbots more trouble than they are worth? Or are they mainly more useful as a support tool vs a lead qualification tool?
