He's just talking about the same voice-activated, computer-controlled house they've been promising us since 1950. How does he know that yet another random voice recognition program will suddenly make it possible?
Because it actually does it?
(and its a reasonable guess that it works as advertised, because Apple has a pretty good track record of waiting until the time is right, and releasing something that is not half-baked)
And, of course, MS and Apple won't adopt it--making it real useful, just as long as all your visitors happen to be using Chrome or some future version of Firefox.
So make it compile to Javascript for browsers that don't support it natively.
Personally I think it would be pretty sweet if Google made V8 support Coffescript natively, both in Chrome and Node.js. But if they were also to build in some of what they've got with Closure, they've got something.
