What are the challenges of creating chatbots?

I am actually developing some chatbots for telegram… imho the most difficult part is to create something persistent and secure. For high complexity projects I spend weeks on testing.

I created a fast one using irssi, does support scripting and there is a eliza perl script that can be used as a start point. I made some quick notes at wiki.cyberporto.xyz/Irssibot

Writing. First chatbot project I worked was for Rose, at R/GA where we had a team of pro copywriters. We had more copywriters than devs! With a chatbot the writing must be absolutely perfect, because that's essentially the UI.

I interviewed a chat bot conversational designer, might be interesting for you. Here it is: https://wannabe-entrepreneur.com/episodes/207/

Are you talking about general chatbots or customer service chatbots? I've worked with a few customer service chats that have decent chatbot functionality. I'm thinking of something like ZenDesk, which has a good suite of customer service tools including a chatbot.

It's a very linear experience for customers, but no code is involved!

Hi there! I have made a few, two that are public: the first is over at https://www.coverletteremails.com and the most recent is at https://newhabitcoach.com

Some of the bigger challenges are dealing with, of course, unexpected answers (replys) from users to the bot as well as gracefully dealing with errors, e.g. a user leaves then wants to restart a chat conversation hours later. Hope that's helpful and happy to answer any questions.
