The current state of chatbots is embarrasingly bad. I still haven't seen a chatbot use-case that can't be solved better with an FAQ section + documentation search and a human as second line of support.
More general virtual assistants (Alexa, Google Assistant, Siri) are at a completely different power level from most chatbots. Most chatbots use cases that I come across are some company thinking that they can replace human support with a language model trained on their custom knowledge base. They expect something as good as Alexa but which also has knowledge about the company's product and the results are always disappointing.
