I watched this some days ago (/. isn't the place to read things first anymore) and came away half impressed and half underwhelmed.
The speech recognition part is nice, and that's understating it a lot given the complexity of the topic. That for a demo they'd use examples they made sure work nicely is a goven. That it can understand fairly complex, disorganized questions is really cute. No, seriously, on this I am impressed.
But it is clearly still very far from human. It lands smack middle in the uncanny valley. It becomes incredibly clear when it talks about population numbers and lists them down to the last digit. Not only is that typical computer-ish, it's also vastly less useful than a human who would tell you "about 80 million".
When I ask my personal assistant device how long it'll take to get to city X, I'm not interested in an answer that says "3 hours, 57 minutes, 48 seconds". I want to hear "4 hours", because we humans understand it's an estimate anyways and a few minutes more or less doesn't matter anyways.
Then again, when I'm building a bomb and ask my phone for the recipe, I'd like to have exact numbers. Again, a human would understand that in this situation, "about 200 grams" is not an ok answer.
This intelligence is still missing, and it's crucial.
