600 bots
How do you actually quantify how many 'bots' your company has? Do you have 600 subtly different versions of chatbot software? Does your software run on 600 different machines? Or as 600 different instances? Or is it just one large distributed piece of software that can manage 600 conversations at once?
It's being positioned that a single unit of 'bot' is equivalent or comparable to a human worker, but the measure of the chatbot software's capability is actually incredibly vague.
