I actually just went through this today. I have a trip I am going on for which my company forced me to go through a travel agency. This resulted in a 20 minute conversation with a travel agent to describe and book a flight plan that took me less than 30 seconds to do on Google Flights. All I wanted to do was click the "buy" button, but no, I had to engage in this mindless conversation.
Not all tasks need conversations. In fact, most tasks are much easier and simpler to do with a mouse or keyboard. The few tasks that do require conversations, are also the complicated requests typically require humans and no bot can handle them today.
