Chat Bots Aren’t a Fad. They’re a Revolution.
Chris Messina

I agree with this. We have ourselves been working on building a conversational bot for commerce for last 1.5 years now and believe chat conversations is going to be the way computer-human interaction will happen. We are trying to make it as free text as possible and solving higher order problem for user. Its a behaviour change and will take some time, but we are observing some exciting trends.
