Bots are the flavour of the season. Everyday, we hear about a new bot catering to domains like travel, social, legal, support, sales, etc. being launched. Facebook Messenger alone has more than 11,000 bots when I last checked and must have probably added thousands of them as I write this article.
The first generation of bots were dumb since they could understand only a limited set of queries based on keywords in the conversation. But the commoditisation of NLP (Natural Language Processing) and machine learning by services like Wit.ai, API.ai, Luis.ai, Amazon Lex, IBM Watson, etc. has resulted in the growth of intelligent bots like donotpay, chatShopper.
