Conversational interfaces just aren't any good, and until they're perfect they won't be useful. The primary issue I've seen (having worked with slack bots) is discoverability, how do you find out what a bot can do without asking lots of open questions? The most useful bots I saw were those that didn't try to be conservsational but had a fixed grammar for commands and questions (along with a good help response). And at least with chatbots you've got the textual context you can scroll back on and read as opposed to trying to keep track of what's happening in a conversation with a non human who you can't see.
