Messenger platform team and the founder of Octane AI (bot building platform) Matt Schlicht recently had a conversation about the future of bots. What's interesting, they don't see Messenger bots going WeChat's way: recreate all transactional experience in one huge platform. Instead of this, they see bots more conversational and personal. I think we'll see some Facebook M implementation right inside Messenger platform later this year.

"Imagine bots that can send updates to your friends for you, tell stories that change based on your reactions, give fans an inside look at what happens backstage at a concert or an awards show. That’s where we want to take bots next. We want to move beyond transactional experiences and make them conversational and personal."
