Amazon’s drone delivery is still a little ways off at least, but we got another glimpse at the future today thanks to a patent application the company filed. The “Unmanned Aerial Vehicle Delivery System” patent describes a system that would allow Amazon’s drones to intelligently reroute to find a package’s recipient through their smartphone.

Amazon’s approach to physical stores is less about shoring up gaps than building a better mouse trap. Amazon thinks it can build a better bookstore based on data.

Amazon’s headcount rose 13 percent in the second quarter of 2019 to a global total of 653,300, an all-time high for the 25-year-old tech giant. But its technical headcount for areas such as Amazon Web Services and its voice technology arm grew at nearly twice the rate of overall hiring in the quarter, Amazon CFO Brian Olsavsky said on a call with investors Thursday.

Amazon’s relationship with the United States Postal Service for deliveries that has come under political scrutiny, and it is looking to take control of more of the process.
