What's really sad is that this has come around multiple times. I remember hearing about intelligent agents coming anytime to MSN Messenger or whatever it was called at the time back in the early to mid 2000s. And people have had this delusion since ELIZA that natural language interfaces are just on the cusp. A good demo is very convincing, but reality creeps in as soon as you use these things for more than a few rote interactions. The only real innovation of the latest generation of natural language interfaces is their ability to somewhat reliably understand the actual words you use. But even that is highly context dependent and limited to straightforward constructions. And it's all built on just having huge massive datasets against which to compare what's being said. But "natural" language doesn't depend on having past analogues. "Natural" language is constantly finding new ways to say things. And I've not seen any evidence we're any closer to that now than we were in 1966.
