SEATTLE — This week, I asked if the grocery shopper of the future — my 15-year-old son, Benjamin — might be interested in checking out Amazon Go. I didn't have to ask twice. The market in the burgeoning Amazon campus near downtown Seattle was the talk of the town.

Word had already spread of the literal grab-and-go store — there are no registers or, indeed, any cash accepted — at Benjamin's high school, where kids stretch the lunch-period limits to snag a salad at the nearby Whole Foods Market, also owned by Amazon. (Amazon's chief executive, Jeffrey P. Bezos, also owns The Washington Post.)

"How about today?" he asked with an enthusiasm usually reserved for opening-night movie tickets.

A Seattle native barely old enough to recall dial-up modems, Benjamin felt none of my Orwellian angst about a cashier-free business where customers are automatically charged for purchases when they exit the store.

"It's not as creepy as Alexa," he said.

We made our way to the store's sleek entrance, where we saw more humans at work than I expected: restocking crews, chipper brand ambassadors, salad-tossers in the food prep area visible from street-level windows.

Entering the 1,800-square-foot store required scanning the Amazon Go app I had downloaded earlier, sliding my iPhone over a plastic-gated turnstile something like a subway entrance. The app ensures anything you take will be charged to your Amazon account. Effectively, it also restricts customers whose incomes don't support smartphones or credit cards.

I beeped Benjamin through the gates, linking his purchases to my account, then scanned once more to follow.

Inside, the market felt surprisingly spare, an upscale but monochromatic convenience store with a camera-jammed ceiling. There was no produce department, beyond some pre-cut packaged fruit. No meat counter. It was like the inverse of a Costco warehouse, every item designed for a household of one or two, from single-serving boxed Duncan Hines mug cake mix to shelves of Amazon-branded meal kits. The selection was squarely aimed at urban workers in the South Lake Union neighborhood, once jokingly and now seriously referred to as Amazonia, who are notorious for prizing speed and ease when they emerge for snacks and meals.

A wall of candy featured an "Amazon Go" bar from Theo Chocolate, Seattle's fair-trade chocolate factory. Boxed pastries came from Seattle's Macrina Bakery and the Essential Baking Company, mainstays at indie cafes. If 69-cent Diet Cokes didn't appeal, there was pressed-rhubarb soda from Great Britain and $3.99 Stumptown cold brew from Portland. ("That's the most expensive coffee ever," sputtered Benjamin, who tries to be frugal with his hard-earned babysitting cash. I had to break the news that it was not.) Packaged salads and prepared foods lined the refrigerated shelves, from butter chicken to tofu banh mi. Several items were sold out, including birthday-cake-flavor Halo Top ice cream.

Customers may have come for the novelty, but they left with full bags. So did we: Benjamin chose pasta salad ($4.99) and iced tea ($1.39). I added a chocolate chip Macrina cookie ($2.29), a 17-ounce box of Honey Nut Cheerios ($2.99) and a two-serving salmon donburi meal kit ($19.99.) The kit made a good dinner, as I'd expect — Amazon long ago hired Jonathan Hunt, formerly one of the city's top caterers. We walked out without incident. Five minutes later, my phone chirped with an itemized receipt, complete with product photos and a time stamp noting our 23-minute and 54-second visit.

"I think this could be a big thing," Benjamin said.

That's been the case with everything else involving Amazon and Seattle, where the homegrown giant has fueled explosive growth, for better or worse. Look one way outside Amazon Go to see the spectacular new "Amazon Spheres," private dome-shaped office buildings landscaped with tropical gardens. Look the other way toward the "Mary's Place" shelter for homeless families that Amazon sponsors in another building, one of the few bright spots in a raging homelessness crisis. Seattle's median home price is now $725,000, unattainable even if the nonexistent cashiers at Amazon Go had earned the city's $15 minimum wage.

Benjamin said if he worked in the gorgeous glass spheres — one of the few ways even a smart, privileged kid could afford to stay in Seattle as an adult — he could imagine shopping at Amazon Go.

Would he miss human checkers?

He'd miss humans at restaurants if tablets replaced servers, he said. He wants human bookstore clerks who know and love books. But grocery-store pleasantries seemed shallow and transactional, and not essential.

To my generational surprise, I agreed. Maybe it's from all the non-Amazon markets that already replaced many humans with self-check kiosks where I scan my own bar codes in incompetent solitude.

The Big Brother aspect of our shopping trip, though, still bothered me. I told Benjamin how I paid cash for prenatal vitamins when I was pregnant with him, to preserve our privacy. In 2001 that felt paranoid. Now it seems prescient — and, to his generation, pointless.

"Amazon could get that information anyway, without the store," he said.

We headed home, and Benjamin's siblings eagerly pounced to see what he was carrying and where he had been.

"It's a new grocery store. It's run by Amazon," he told 10-year-old Nathaniel.

"It's run by robots?" Nathaniel said.

Benjamin explained the scenario. Nathaniel seemed more impressed than concerned.

"Robots have taken over the Earth," he said.

"Kind of," replied the most benevolent big brother he'll ever have.

Benjamin took his pasta salad and iced tea out of the bag, and took them to his room — to have some privacy while he ate.
