Continually whittling down the friction involved with bots will make the interface much more compelling. This can be as simple as having credit card information saved rather than having to type it out with each transaction. The other more complex way of reducing friction is enhancements in natural language processing. Being able to talk to a bot without having to repeat yourself (hello Siri) will drive a wave of mass adoption. It won’t be Facebook’s current iteration of messaging bot that causes a seismic shift, but I think the concept of bots in general offers a glimpse of what is to come once the nascent-stage usability issues are solved.
