Amazon’s blockbuster deal to buy Whole Foods Market for .7 billion shocked the foundation of the grocery/retail world, and it also put grocery delivery startup Instacart in an awkward spot.

Amazon’s Jeff Wilke, CEO of the company’s Worldwide Consumer Business, made one of the biggest announcements of the week, unveiling a fully-electric drone that can fly up to 15 miles and deliver packages under 5 pounds in less than 30 minutes. Wilke also showed the array of different sensors that are built into the drones, in an effort to ensure safety during deliveries.

Amazon’s latest misstep is the abrupt, and still unexplained, shuttering of TenMarks, a math and writing software startup it purchased in 2013 and announced in 2018 it would close the following year, leading to a lot of frustrated, Twittering teachers. That was preceded by the forever-in-beta Amazon Inspire, an educational resource sharing site launched in 2016 but kicked hard in the knees immediately afterward, when a handful of copyrighted items were found posted on it. A year later, the company also lost its K-12 education general manager, who had come to Amazon with the TenMarks acquisition.

Amazon’s system, as described, would have a key advantage over big-box warehouse stores: it’s possible to buy in bulk from Amazon without having to get in the car, drive all the way to a massive warehouse, and then wander the aisles hoping to pick up a five pound bag of trail mix and an 18-pack of paper towels.

America is also approaching half a million confirmed cases of COVID-19, with 496,535 as of 8:30 pm (0030 GMT Saturday), an increase of 35,098 in the past 24 hours.
