I disagree. Chat bots can be superintelligent about fact-based 'How do I do this?' type questions in a B2B context. It can "know" vastly more about complex platform-type products than any person can. In our case, we offer both chatbot for 'How do I do this?' type questions, and contact a human support agent for 'I have a discrete problem I need help with?'. Customers love it.
I don't usually contact customer service to ask them how to do something. I usually do so because I have some issue with whatever situation and need someone to resolve it.
This is true of technical customers, which only a small percentage of people are in a B2B or consumer context. Non technical customers behave very differently.
