Can you explain more about what you mean by "able to handle the ambiguity of human language"? Such a claim goes far beyond language processing itself. Such a capability would have to involve cultural and interpersonal dynamics, domain knowledge, and definitive agency on the part of the computer.

And all of _that_ is just to interpret sincere, honest attempts at communication. Can it safely and appropriately handle humor, irony, and sarcasm? What about coordinated malicious attacks?
