Uber would've been impossible if you had to lug around your laptop and connect to a cafe's wifi to call a car. That came from its founders having iPhones and the power of the App Store to make an idea possible.
It would not have been successful if you had to lug around laptop.
But it would certainly have been possible. And the decade-old existence of taxicabs that could ordered with a phone call (even from a dumbphone) or hailed on the street is evidence to the contrary.
Here's the thing: The revolution that Uber brought to the table is
not the form factor with which your order your ride.
Uber has simplified and automated the exchange the of routing information (where you are, where you want to go, how long it takes) and replaced the human middleman with its limited "database". And they've developed a successful marketplace matching algorithm and system to assign drivers to riders.
You could literally use a GPS tracker and a dumbphone to call your Uber service number. Give them your GPS coordinates or tracker number and they'll quote you a price over the phone. You accept - that's it.
It can get better with AR. You come out of a restaurant onto the street, ask Siri for a ride and it shows you nearby cars. Hail one by raising your arm (even if it's still a block or more away) and you'll see it highlighted as it approaches you.
...and crash into the nearest lamppost on the street and/or have your wallet stolen, cause you're distracted by your head-worn AR glasses.
Also, there's much cheaper ways to identify your Uber. You could literally have a small digital display with a number - or your name on it. It's not that hard to identify - today's technology is good and convenient enough.
You're at a bar and people there who have their AR Tinder enabled can like each other. You see a hot girl, a red heart hovers over her, you see her profile and wink at her in the app. It's a match! She had liked you earlier.
Tinder models get less right swipes with glasses.
Then again, some facetuning algorithm could probably digitally "remove" the glasses, couldn't it?
You're travelling in a new city and ask Siri to get you a rental car, the ZipCar app pops up and shows you walking directions to the closest car. As you arrive in the lot, a little bouncy arrow points at the car which glows as you approach it, it unlocks and you get in and drive away, with directions to your destination in your field of view and your Apple Music playlist playing on the car stereo with zero setup or plugging in.
Apple Music doesn't require a headset or AR glasses. And identifying the car isn't that hard. Have you ever seen those car key fobs that make a car's lights blink, when it's locked or unlocked while parking?
Look at it and position furniture virtually in your space. You decide to go to IKEA to get a sense for the furniture in real life. As you walk the aisles, you wonder if a couch you're looking at will fit. Your glasses had previously taken the measurements of your space and confirms it. You're now standing in your virtual living room in the IKEA showroom with the real couch there for you to touch and get a feel for in your space.
Why drive the long way to IKEA - when IKEA and it's couch can come into my living room at home?
I'll just take a picture with my iPhone - which, with its protruding camera cutout has better cameras than my smart glasses, send it to IKEA/the IKEA app. They'll do spacial recognition on it and let me virtually position a couple of couches on my computer in that room.
Very few people had been wearing smart watches at that time, this was an entirely new category for the general public
I'm still seeing a lot of people wearing them - but rarely using them for their "smart" functionality.
👉 Don't get me wrong, I'm not a naysayer or hater. I honestly appreciate your futurist thinking and your post providing concrete examples. I am, however, also a believer in technology that's "good enough" or even just "simple enough". And people and businesses being too wary or lazy to switch from or improve on such technology. I just don't see the killer application.
