How close is Google to building a Paul?

As someone who recently got a haircut, Google's presentation yesterday at I/O really resonated with me. Finally, a service that can make phone calls on my behalf and negotiate appointment times with hair salons. Google's Duplex technology even uses the word "um" and sometimes misunderstands what people on the phone are talking about. It got me thinking: how close is Google to replacing me altogether? For instance, Google can already write most of my text messages, and now it can help compose for me. Could it write my Verge articles, too?
