Hello! Thanks for sharing your opinion. You are right; this article doesn’t provide an in-depth overview of all the problems that businesses face while trying to create their own chatbots. We didn’t aim to cover all the pitfalls of the chatbot development within such a short piece :) We wanted to provide a high-level overview of the problem and share our vision on its primary cause — lack of a clear vision of what businesses want from their smart assistants. You may want to check a related article we published recently in our R&D blog dedicated to NLP engine development problems.
