Street view is an insane project. Whoever thought of it is crazy and whoever approved it even more so. Kudos!
Back when google had ambitions. Now they’re dead walking.
@@mohamedfahad2364 you can also think of something crazy to do and create it. Google bought these crazy and ambitious projects and improved it. Build your one and sell it to goole to improve.
Shazam was way ahead in terms of Engineering when they launched it on nokia phones. Glad they survived and we see it all iPhones nowadays.
shazam is so useless it cannot recognise any song i want to know about. in my experience, acr cloud performs so much better
@@kiyoponnn Finds almost all songs I want. Even really hard ones
iPhones? It's not just on iPhone
@@Oystein87 yeah. I cringed too. Some people are so deep buried in the apple universe.
@@caty863 So true... I in general avoid Apple. They don't fit my needs and are more locked than better alternatives.
And Apple is not really a customer friendly company either.
Shazam's story is incredible, I did not know it has been around since the early 2000s.
My inner nerd has really been satisfied by learning and understanding how some of the apps actually work. makes one love tech even more.
I am happily surprised that Shazam started before the era of smartphones; that's impressive. their tech works like magic. I still like to see peoples' jaws drop when I show them I can open my phone and instantly get the scrolling lyrics of the song playing in a bar. I wish all songs on the platform had that feature!
Yeah that's crazy, launched at 2002... way ahead of their time
WSJ Tech Behind is such a great series man plz never cancel this feature
45:05 that picture on the wall is crazy
Crazy? I was crazy once...
These Tech Behind series are incredibly well made! WSJ - Please keep up the great work!
A little guy in your phone does all the work
WSJ shd do more of these!
I love these type of videos/docs! It's insane how far we've come in the last 20 years.
Very informative, I always wondered how apps like Spotify worked.
The coffee shop at 45:08 has an interesting taste in interior decoration.
Was about to say 😂😂😂
its crazy to have a peek inside the working of these great tech. Loved this vid
I remember using Google Earth on my iPhone 4. Then I was blown away by Google Earth VR on PC. But then Google abandoned it, like all of their other projects. Wish they updated it brought it to Oculus Quest and Apple Vision Pro.
don't know about the VR, but pretty sure Street Maps as well as Google Earth is still working and being improved.
Still use Google Earth all the time
@@AlphaGeekgirl I think you mean Google Earth Enterprise, the platform that companies could use to host their custom maps.
Google Earth is readily available for the Oculus Quest in VR. Not the enterprise version, the regular version.
@@pbase36 there is no Google Earth on the Quest store. There is only Google Earth for PCVR, which hasn’t been updated for years.
All I can say is technology is fascinating. Thanks for the vid.
Now that was an excellent collection of extraordinarily interesting technologies. Thank you!

how wide do you want your lens?
YES
Sony Ericsson phone used to have TrackID, very similar to Shazam, and it was already there more than a decade ago. It is amazing to witness that now computer can recognize a music from us humming some notes, like Google Assistant does.
This video makes me to start using Spotify because i love listening to songs that sounds the same I love that
just created an account because of DJ. but i cant find it
😢
This is so helpful. Great Informative Video. 👏🏻
I can’t believe Spotify is showing us the way their algo works. That’s insanely fascinating
It's absolutely incredible how far The Technology has come.
Very interesting show !! Great to learn about this products we use everyday.
I cant wait to see the sphere! 😮❤🎉
Thanks for the video
Quite elaborate discussion.
Good documentary, thank you WSJ.
I love that Dermot Kennedy was listed in the Spotify part
Excellent documentary.
I appreciate these unsung heroes who work tirelessly to enhance standards of our life. 🙇🏻
I love Shazam it’s always among the first downloads every time I change phones that and Pandora music always on the lookout for new bands
are you using iPhone ?
cause if not then why exactly would you download Shazam, when you can just ask Google Assistant what song it is, and it will give you pretty accurate results, considering it has access to whole CZcams/CZcams Music library.
edit: I used to use Shazam but I remember few years ago, you need to play song for it to recognize while Google can find it even with just HUMMING.
Maybe now Shazam can do that as well, but at that time only SOUNDCLOUD and Google were capable of it, and SOUNDCLOUD was very bad at it and also it's library was pretty bad.
So I started using Google and now just don't need to download any app anymore.
For me is Shazam & Spotify 😅
Great video, I liked & downloaded.
I also appreciate the chapters & transcription.
This was such a great video, so many things I've been curious about
This is great and awesome content! Another AI and infrared that could be useful would be Traffic lights and rerouting traffic patterns
LOVED THIS
Tap to pay is nice. Usually you have to stick the card in and then type the code, but with tap you just touch the machine and can even move the card away and back into the wallet, and when it’s in your wallet first then the transaction are confirmed (paid). and you can easiler move on, instead of have to rush putting the card away
Appreciate this detailed observation
But that also means any body with active rfid device can get your money by just sneaking close to your wallet. Unless you have aluminium line wallet in that case u r swfe it doesnot allow waves to pass
You have to be surprised with some new service taking over and rendering you bank contactless payment inactive on your smarth phone, but not using a card.
I do love Spotify more after watching this, specially the color representation. This is good!
This was really interesting.
Thank you
Poppy Crum...could listen to her for hours 😂. Excellent at public speaker / breaking down complex info
Thank you very much, useful information and also interesting or engaging
Great video, very interesting 👌🏾
Very interesting! Thanks
"Trust us bro, we are using your data in a moral way" yeah right
shazam coming up before even apps existed is so cool!
Very educational video, it helps traders try out new strategies, thank you.
Good applications, will change life a lot.
This was hilarious and informative! Sub just because of this!!
I will say, apple pay has been a real lifesaver on occasion. I have forgotten my wallet but never my phone. Overall I really enjoyed this episode. Thanks.
The idea of Collaborative filtering from Netflix changed whole worlds of recommendations.
One thing I dont get about google maps and something they need to improve is why dont they update speed/red light detection cameras since they can detect changes in road signages, buildings, amd road changes. Surely it cant be a legal thing because apps like Waze have always detected them
Great video. Thanks WSJ. Does anyone know if there are any schools or courses that give people hands on experience with understanding how technology like this works? I’d love to go further into it after this video.
I believe it all starts with learning advanced maths and coding . By learning a coding language such as Python you get to build software applications which are at the heart of the devices we use
Here is the syllabus for a course I took at Columbia University on Policy for Privacy Tech. The readings prescribed by Professor Cummings were fascinating: rachelcummings.com/wp-content/uploads/2021/12/IEOR-4575-Syllabus_final.pdf
If you want to pursue a career in tech like this, you might want to look at enrolling in a coding boot camp or pursuing a masters in electrical engineering/software engineering
Search up ‘Rachel Cummings, Policy for Privacy Technology Columbia University”. Her syllabus will pop up. I took this course in my last year of college and the readings she shared were very insightful. It changed my perspective on tech policy and how we handle big data!
Me: I want Adam Savage.
Mom: We have Adam Savage at home.
Adam Savage at home: 2:33
I thought the LED wristbands were gonna be some next gen Google Maps tracking 😭
google maps is just an incredible piece of technology
Заносы лютейшие!) давай больше таких видосов) хочется глянуть как ты играешь с большим баликом)
This was interesting.
Good material, but it's hard to watch because of bad montage
May you please add some extra seconds when you change topics? Hard enough to be switched from one theme to another with no pause
Soo... this Spotify, algo has an API? So potentially, the sonic char's and temp structure... for latest songs = could predict next big hit? (with a little Ai too)
My android phones does a "shazam" through Google assistant. I just say, "hey Google, what is this song?", and it answers in a few seconds.
So i wonder if they're licensing technology from Shazam, or actually duplicating it.
If seems insane to replicate something so complex, but then Apple made it's own map system, so companies definitely do it.
I am pretty sure Google made it's own thing.
Cause a few years back when I used to use Shazam, it didn't recognize any songs when HUMMING.
it needed a song playing to recognise it.
At that time only SoundCloud and Google were able to recognize song by just HUMMING.
and SoundCloud was pretty bad at it and had very few songs in the library as compared to Google which has the whole of CZcams.
I am pretty sure they made their own, cause that was my main reason to shift from Shazam to Google Assistant and now I don't need to download a separate app for this.
I just hope they give an option to make a SHORTCUT on my homescreen which will directly start song recognition, instead of needing to start the Assistant and then asking it to recognise a song.
edit: just found out you can make a shortcut on homescreen for that.
@@MarcSpctr interesting. So I don't need to download Shazam to get the best, Google is probably as good or better.
I use Google Assistant for every song that I want to get ID'ed. The humming feature is heavensent. I only use Shazam when Google Assistant failed to identify the song (which is a rare occurrence)
@@MarcSpctr how do you speak to the google assisstant to tell it to search for a song in the club? it's so noisy and you'd look weird to shout to your phone when you are sitting in the cloud. Shazam's interface is much better. I am pretty sure shazam also has access to CZcams songs; the API is free. Besides, does Google Assisstant have the scrolling lyrics feature? that's what I like most about Shazam.
Y'all should do a story on why Walmart refuses to adopt tap-to-pay...
Man these videos are cool and knowledgeable but I wish they went more in depth
7:52 What kind of person sticks the suction cup phone holder to the screen???
In a few months you will come to Mozambique to see my business. Praise God!
The spotify dj feature was pretty cool at first until it kept repeating songs
the shazam guy's right nostril is huuuuuge.. wonder what kind of activities he does on the weekend ❄❄🤣🤣
@7:52 Did anyone else notice the lady with her phone mount suction cupped onto her navigation screen
Images from drones, the future?
Nice to have explained why ANC ruins my music experience. I rather have good passive noise cancelation
Record migrant intake does reduce standard of living. We are in a GDP per capita recession. There are too many humans for the current infrastructure levels. There is more congestion on our roads, hospital/ambulance wait times have increased, rental vacancy rates are at record lows, rent prices are exorbitant, and house prices are increasing despite interest rate rises. So, yes, the standard of living is drastically declining due to the unsustainably high immigrant intake levels over the last 2 decades (particularly the last 2 years).The migrant intake levels needs to drastically drop.
No those be the ones we last meet
So the majority of us say have kids and have invested in Crypto. We’re possibly not that well invested and the price you ask for the FFA is more than say what people have invested.
You spoke of an investment/trading opportunity which can only be viewed being a member on the inside.
So how about next time revel it on your channel and then the gains could be used to invest in your company to start things off.
I don’t trade or want to get my head around it, I’m just investing and watching. What you think BTC will do.
Also thank you Steve and if I’ve offended you I apologise, it’s just a thought for myself and what possibly other might be in. Thank you
This ecosystem has persisted throughout the years in a continuous manner. Pretty incredible how much modern technology has improved.
I am speechless 😮😮and not now at 92 years of age !!
14:19 River Plate ⚪🔴⚪🇦🇷
How about just not making my destination address disappear when I get close to it. Then I have to enter it again when I’m trying to narrow down to the exact driveway.
Google should use drones for capturing images, def cheap in power etc, compared to their alternatives.
Imagine if they had a sphere camera during the D-Day landings...
The thing with having nfc active tech in phones doesn’t make it more easy for people with malicious intent to for example take advantage of the busy hours in public transport and steal money/info just putting their phones back to yours?
Nio is the Apple of EV❤❤❤
Map info , do the origin of info, gathered, is it paid for?ok
Why or how can the spotify lists off? Choose what i want.
US was slow to adopt tap to pay because of tipping culture
Spotify still does not give me relevant music recommendations. I even manually entered my entire music collection into it, liked all the songs, and it still does not know how to give me new songs that I will actually like. CZcams Music, on the other hand, just knows without me entering my entire music library manually. I discovered so much new music due to CZcams and YT Music.
Problem with tap to pay is it's half the time faster the other half the machine freaks out for twice as long as the other choices.
Sometimes when we are too nerd we forgot other basic attributes such as family

16k rez so four TVs in the sphere.
22:02
It will get rejected at 60k and bottom around 43k. Smart money is always smart. If we want 350k+ we have to short until retail starts buying. That will be around 43k
they did not discuss any technology in google map's case that how algorithm works and sort the results for users.
Map info , do the origin of info gathered, is it paid for?
If the service is free your information is the product that's being sold.
Somewhere a nursing home is missing a resident.
Seem like a Native advert for several tech companies. I wonder if WSJ was paid for these "Stories"

Google maps rocks
“AirPods Pro…” while showing a pair of AirPods 3
how? advanced technology
Bro is going to hit a million followers before they show the footage 😅
I don't know what to suggest to see it in my city 3:40 but I let them know with GTA 6 release with a high suspension car in a city. Mostly closely it is SEL Concert, but I can not lie - there would be some riot at that concert. If you remember you have bought some Žalgirio Arena tickets, so that is that thing in a VSCoder Value. Learn as much as you are able seeing that Music UI and you have to let choir masters to see at least some basic classical music letting them understand it as some baseline. So how am I changing your lives there if I don't have any businesses here BLC?
Check collage students buildings with this ensemble data 5:05 and there is some deep ocean. You can do it 7:15, but it's not some alone job and must be planing and if it is a game must be playable for a long time until next release. It could be done depending on those dances and choirs you have here, but how can these Kaunas Mayors help with such task? It could be educational making them learn how to use Unreal Blueprints, because Symfony - Laravel has it as part of it's database migration. Closest thing would be ask President for support, but would a journal try to reach that unfriendly channel in the otherside of the world next to some flight emulator and some PCBboards?
"... we have millions of people's contributing..."
Sure, contributing... lol
always preferd the nokia mapps app over the google maps app.
However, it has a little BS on it. I have been a ferry commuter riding a scooter (the ferry carries scooters also) for six years. Always sharing location. Google never added the use of ferries for motorcycles and scooters in its suggested directions for a destination that could be faster and cheaper.
Tech-company offices always look like kindergartens. lol
