I suppose it shouldn't bother me that the people doing that are 'business users' but I have to wonder if adults these days are so illiterate that they can't read through 20 jira tickets and categorize them in less than an hour.
This leaves more time to spend arguing with the chatbot about miscategorized tickets; the chatbot exclaiming "you're right, I'll do better next time" and then making the same mistake tomorrow.
If they can automate it, then they can spend that time doing something more useful, like researching Jira alternatives.
