Salespeople exist because people have questions and want to be reassured.
Really, they just need some information that will benefit them but aren’t sure of how to ask to get said information.
So what if you created a system or game that answers questions, gives the needed information, and reassures the user? You could conceivably structure a system where your customers were free to explore, and prompted to find answers on their own.
If you created such a system or game, instead of sending a sales person next time, you could simply plug in prospects to your system and let the automated process take over.
