Take AmazonGo, the A.I.-powered convenience mart that opened 10 locations in cities including Seattle and Chicago last year, with plans to evangelize New Yorkers next. Cutting errand time back considerably, the store offers "JustWalkOut" shopping for groceries and meals. How it works: Download the free app, scan a QR code at the entrance, grab items off the shelves and exit through the turnstiles. By the time you receive a receipt in the AmazonGo app, you're halfway to the car. At less intelligent stores, you might soon be able to grab a cart that lets you checkout and bag items without a wait.

A recent Refinery29 piece by lifestyle editor Cait Munro confirms what we seasoned homebodies have always known: Staying at home is cool. That declaration is based on a recent survey from market research firm Mintel that suggests almost three in 10 young millennials (people aged 24-31) prefer drinking at home because it takes too much effort to go out. And they're not alone--55 percent of Americans of all ages would prefer a night in with a glass of rosé over a bar crawl. The survey participants cited everything from wanting to drink in a relaxing environment to a desire to save money as the impetus behind their general aversion to bars and clubs, but the millennials Munro interviewed herself offered another rationale for the shift from the streets to the sheets: online dating. What Munro calls the Netflix-and-Chill factor can be accurately described by this quote from Jenifer Golden, "a self-proclaimed'older millennial' and one half of the duo behind the podcast It's Complicated" who says, "It's the whole dating idea of Netflix and like, I'm going to sit on my couch, watch all of the things that I could possibly watch and drink all my wine from Trader Joe's. Why would I leave my house? I can invite somebody over to hang out with me."
