I am wondering if this because Siri is so bad, people think of Siri now as a voice activation method rather than an AI assistant as it was intended.

The demo is so good, what was once a sci-fi / Iron Man Jarvis services is now real. I don't follow AI closely, but all previous iteration were at best ask and answer type of services. It wasn't real conversation. And whatever flaws it may have now, at the rate of improvement within a few iteration it will surely reach good enough stage for majority of people.

This is also scary. Not just for adults, but for kids. How they could become even more isolated.

I remember the PC era, the internet from Information Super Highway to Web 2.0 Then Smartphone. It may have been obvious to many but AI really is something much bigger than all the previous three, perhaps combined. And it is also the only one that I think is scary.
