What struck me the most was the business decision from Google to have it make reservation calls, and not take them. Granted, the technical complexity between the two might be an order of magnitude, I don't know.

They are purposefully "giving" it to millions of customers and rolling out features with time, instead of holding out for more research and actually selling a phone assistant system to businesses. I think this speaks volumes in and of itself, and I would interpret it as a sign that competition might not be so far behind.

Or maybe I'm reading this wrong?
