Author here, great to see all the feedback! And I agree that the title can be read in different ways. But anyways: it was hard for me to find simple examples of how to build a more advanced chatbot. I think the Watson API is a great service to integrate with. The telegram API is very easy to use, powerful and fun. So the combination has potential for cool projects. I wanted to motivate bot makers to utilize whats out there and not create one copy cat and porn bot after another.

Moreover, the Watson API has good documentation and examples plus a variety of cool services that can enrich the chatbot experience. Wanted to provide a starting point if someone is interested in this topic.

Of course all the artificial intelligence is exclusively provided through Watson. I'm not saying that you can beat the Turing test with 50 lines of code or without external APIs. Just scratching the AI surface here ;-)
