But I think everyone building bots wants to go beyond that. I work on bots at Intercom and believe we can build bot experiences much better than traditional search.
At the same time, I think google search is heading a conversational direction - context now carries over between queries, and it seems like that naturally trends towards more conversational or agent interfaces.
But it's quite amazing how easy it has become to use such complicated technologies to build useful products!
(To be clear, I am not trying to belittle what was done in the blog post.)
