How hard is it for a computer to understand the sentence: "Tea, Earl Grey, Hot"? That takes care of 90% of the use case scenarios right there. Next is "Computer, initiate auto-destruct sequence" is the next 8%.

I like that the voice over was done by an actor who played a Bond villain (Robert Davi).

A site like Facebook isn't computing the value of pi or calculating jump coordinates for the Galactica, things that would benefit from a more efficient implementation. I don't know anything about Facebook's site, but many web applications use the application layer to essentially pull data from and send data to databases. Parsing data back and forth typically isn't sped up with C++ or even C that much compared to PHP. All many PHP sites do is draw HTML, and a lot of SELECT, INSERT, UPDATE, and DELETE queries. Hard to imagine C++ having a big impact on that, certainly not 10:1.
