00:00:07.759 --> 00:00:13.920
it's friday evening right after work and you've run low on provisions yet again

00:00:12.400 --> 00:00:17.440
maybe the grocery store is packed to the gills with customers and even the

00:00:15.440 --> 00:00:21.439
self-checkout lines are long or maybe you have to buy something that

00:00:19.279 --> 00:00:25.199
you'd rather not anyone see you leaving the store with hmm

00:00:23.680 --> 00:00:29.279
so wouldn't it be nice to have a way around the crowds the long waits the

00:00:27.680 --> 00:00:32.880
vague sense of embarrassment you get when you had an 18 pack of toilet paper

00:00:31.519 --> 00:00:37.600
to the cashier so this is one of the ideas behind

00:00:34.719 --> 00:00:41.840
amazon go a new concept grocery store that allows you to walk in grab what you

00:00:39.600 --> 00:00:45.920
need or maybe some things you don't and walk right out without any pesky human

00:00:44.800 --> 00:00:50.960
interaction and to be clear it isn't just a glorified place for you to pick up

00:00:49.280 --> 00:00:55.280
things you've already ordered like we've seen with amazon's locker system the

00:00:53.280 --> 00:00:59.280
only pre-visit setup is to download the amazon go app on your phone and link it

00:00:57.360 --> 00:01:02.480
to your amazon account when you walk inside you'll scan your phone against a

00:01:00.879 --> 00:01:07.360
turnstile and when you're all done shopping you just walk out amazon has

00:01:05.360 --> 00:01:11.920
even put up signs everywhere saying this exact thing turning just walk out into a

00:01:10.479 --> 00:01:16.640
slogan to sell customers on the simplicity but how exactly is it keeping

00:01:14.640 --> 00:01:20.240
track of what you buy well some of the inventory control features are fairly

00:01:18.320 --> 00:01:24.159
obvious like weight sensors under the products kind of like what you see in an

00:01:22.080 --> 00:01:26.960
overpriced hotel minibar that can detect when a box of cashews has been lifted

00:01:25.920 --> 00:01:31.040
off of them but unlike that system amazon's is smart

00:01:29.520 --> 00:01:35.200
enough that it won't charge you if you put it back but much of the real magic

00:01:33.280 --> 00:01:39.040
actually happens above you so if you look up in the rafters you'll see an

00:01:37.040 --> 00:01:42.960
array of hundreds of cameras and sensors not only keeping an eye on things but

00:01:41.280 --> 00:01:46.399
feeding information about customers moving around the store to servers that

00:01:44.479 --> 00:01:49.439
use machine learning to determine exactly what you've put inside your

00:01:47.840 --> 00:01:54.960
shopping bag or your backpack or whatever now aside from saying that they don't

00:01:52.720 --> 00:01:58.000
use facial recognition in this process and that some products are tagged with

00:01:56.479 --> 00:02:02.320
special patterns to help the cameras pick them out amazon has been relatively

00:02:00.479 --> 00:02:06.960
tight-lipped about exactly how this process works which makes it either a

00:02:04.880 --> 00:02:11.120
little magical or a little creepy depending on your perspective

00:02:08.800 --> 00:02:15.360
one thing we have seen though is that it does appear that profiling a customer's

00:02:13.120 --> 00:02:19.840
body shape and size is part of this special sauce as one of the issues that

00:02:17.599 --> 00:02:23.280
amazon's engineer tangled with prior to launch was the system mistaking one

00:02:21.760 --> 00:02:27.360
customer for another if they looked physically similar now these little

00:02:25.040 --> 00:02:31.680
imperfections mean that amazon staffers are still supervising all of this

00:02:28.959 --> 00:02:35.599
automation plus they need a surprisingly large number of human employees at the

00:02:33.519 --> 00:02:38.959
store to help customers prepare ready to eat meals and check ideas for those of

00:02:37.599 --> 00:02:42.800
you who want to partake in adult libations apparently the state of

00:02:41.040 --> 00:02:47.120
washington hasn't decided is ready to trust computers to keep smearing off ice

00:02:45.120 --> 00:02:50.160
out of the hands of unsuspecting college bros

00:02:48.160 --> 00:02:54.080
but wait why am i specifically calling out washington state

00:02:51.680 --> 00:02:57.360
well the only amazon go store currently open to the public is in downtown

00:02:55.519 --> 00:03:01.440
seattle in one of the same buildings that houses amazon's headquarters and

00:02:59.440 --> 00:03:05.519
amazon has been cagey about providing details about his plan to expand to more

00:03:03.200 --> 00:03:08.879
locations in the future probably because outfitting a store like this not only

00:03:06.959 --> 00:03:13.280
requires a huge financial commitment upfront but according to amazon also a

00:03:11.440 --> 00:03:19.200
ton of computing resources to function properly so it won't happen overnight but amazon

00:03:16.959 --> 00:03:22.640
is betting that their new go store might resemble the future of retail and

00:03:21.120 --> 00:03:27.200
there's been lots of speculation that we might see similar tech employed at whole

00:03:24.319 --> 00:03:30.720
foods which amazon now owns an idea that's already catching criticism for

00:03:29.040 --> 00:03:34.720
reasons from concerns about huge amounts of data mining to automation putting

00:03:32.720 --> 00:03:37.760
people out of work to making it easier to overspend since there's nothing

00:03:36.400 --> 00:03:42.159
stopping you from walking out with perhaps more than you need however you

00:03:40.319 --> 00:03:46.159
might feel about all that though we tried it and if you find yourself in

00:03:43.599 --> 00:03:49.760
seattle anytime soon i'd say it's worth giving it a shot so let us know down in

00:03:48.159 --> 00:03:53.120
the comments if buying some fancy expensive cheese without the rigmarole

00:03:51.599 --> 00:03:58.239
of going through a checkout made you feel liberated or just kind of funny

00:03:55.599 --> 00:04:01.840
smelling and broke but speaking of being broke or hopefully

00:04:00.080 --> 00:04:04.640
not being broke are you racing against the clock as a freelancer it's

00:04:03.360 --> 00:04:09.040
