PART ONE THE POWER OF CONVERGENCE
CHAPTER ONE Convergence
Flying Cars
The Skirball Cultural Center sits just off the 405 Freeway, on the northern edge of Los Angeles. Built atop the thin spine of the Santa Monica Mountains, the Center offers spectacular views in nearly every direction, except for the freeway belowâwhich is bumper-to-bumper for miles on end.
Of course it is.
In 2018, for the sixth straight year, Los Angeles earned the dubious honor of being the most gridlocked metropolis in the world, where the average driver spends two-and-a-half working weeks a year trapped in traffic. Yet help may be on its way. In May 2018, the Skirball Center was ground zero for Uber Elevate, the ridesharing companyâs radical plan for solving this traffic: their second annual flying car conference.
Inside the Skirball, giant screens displayed a night sky dotted with stars that slowly faded into a blue sky dotted with clouds. Beneath the clouds, it was standing room only. The event had attracted a motley crew of the power elite: CEOs, entrepreneurs, architects, designers, technologists, venture capitalists, government officials, and real estate magnates. Nearly a thousand in total, dressed in everything from Wall Street slick to eternally casual Friday, all gathered to witness the birth of a new industry.
To kick off the conference, Jeff Holden, Uberâs (now former) chief product officer, took the stage. With curly brown hair and a gray Uber Air polo shirt, Holden had a boyish demeanor that belied his actual role in the affair. This event, in fact, the entire concept of getting Uber off the ground, was Holdenâs vision.
It was quite a vision.
âWeâve come to accept extreme congestion as part of our lives,â said Holden. âIn the U.S., we have the honor of being home to ten of the worldâs twenty-five most congested cities, costing us approximately $300 billion in lost income and productivity. Uberâs mission is to solve urban mobility.⊠Our goal is to introduce an entirely new form of transportation to the world, namely urban aviation, or what I prefer to call âaerial ridesharing.â â
Aerial ridesharing might sound like sci-fi clichĂ©, but Holden had a solid track record of disruptive innovation. In the late 1990s, he followed Jeff Bezos from New York to Seattle to become one of the earliest employees at Amazon. There, he was put in charge of implementing the then zany idea of free two-day shipping for a flat annual membership fee. It was an innovation that many thought would bankrupt the company. Instead, Amazon Prime was born, and today, 100 million Prime members later, that zany idea accounts for a significant portion of the companyâs bottom line.
Next, Holden went to another startup, Grouponâwhich is hard to remember as a disruptive enterprise today, but was then part of the first wave of âpower to the peopleâ internet companies. From there, he went to Uber, where, despite the turmoil the company experienced, Holden strung together a series of unlikely wins: UberPool, Uber Eats, and, most recently, Uberâs self-driving car program. So when he proposed an even zanier product lineâthat Uber take to the skiesâit wasnât all that surprising that the companyâs leadership took him seriously.
And for good reason. The theme of the second annual Uber Elevate wasnât actually flying cars. The cars have already arrived. Instead, the theme of the second Uber Elevate was the path to scale. And the more critical point: That path is a lot shorter than many suspect.
By mid-2019, over $1 billion had been invested in at least twenty-five different flying car companies. A dozen vehicles are currently being test-flown, while another dozen are at stages ranging from PowerPoint to prototype. They come in all shapes and sizes, from motorcycles stacked atop oversized fans, to quadcopter drones scaled up to human size, to miniature space-pod airplanes. Larry Page, cofounder and CEO of Alphabet, Googleâs parent company, was among the first to recognize their potential, personally funding three companies, Zee Aero, Opener and Kitty Hawk. Established players like Boeing, Airbus, Embraer, and Bell Helicopter (now just called Bell, a reference to the future disappearance of the helicopter itself) are also in the game. Thus, for the first time in history, weâre past the point of talking about the possibility of flying cars.
The cars are here.
âUberâs goal,â explained Holden from the stage, âis to demonstrate flying car capability in 2020 and have aerial ridesharing fully operational in Dallas and LA by 2023.â But then Holden went even further: âUltimately, we want to make it economically irrational to own and use a car.â
How irrational? Letâs look at the numbers.
Today, the marginal cost of car ownershipâthat is, not the purchase price, but everything else that goes with a car (gas, repairs, insurance, parking, etc.)âis 59 cents per passenger mile. For comparison, a helicopter, which has many more problems than just cost, covers a mile for about $8.93. For its 2020 launch, according to Holden, Uber Air wants to reduce that per mile price to $5.73, then rapidly drive it down to $1.84. But Uberâs long-term target is the game-changerâ44 cents per mileâor cheaper than the cost of driving.
And you get a lot per mile. Uberâs main interest is in âelectric vertical take-off and landing vehiclesââor eVTOLs for short. eVTOLs are being developed by a plethora of companies, but Uber has very particular needs. For an eVTOL to qualify for their aerial ridesharing program, it must be able to carry one pilot and four passengers at a speed of over 150 mph for three continuous hours of operation. While Uber envisions twenty-five miles as its shortest flight (think Malibu to downtown Los Angeles), these requirements allow you to leap from northern San Diego to southern San Francisco in a single bound. Uber already has five partners who have committed to delivering eVTOLs that meet these specs, with another five or ten still to come.
But the vehicles alone wonât make car ownership irrational. Uber has also partnered with NASA and the FAA to develop an air traffic management system to coordinate their flying fleet. Theyâve also teamed up with architects, designers, and real estate developers to design a string of âmega-skyportsâ needed for passengers to load and unload and for vehicles to take off and land. Just like with the flying cars, Uber doesnât want to own these skyports, they want to lease them. Once again, they have very specific needs. To qualify as Uber-ready, a mega-skyport must be able to recharge vehicles in seven to fifteen minutes, handle one thousand takeoffs and landings per hour (four thousand passengers), and occupy no more than three acres of landâwhich is small enough to sit atop old parking garages or on the roofs of skyscrapers.
Put all this together, and by 2027 or so, youâll be able to order up an aerial rideshare as easily as you do an Uber today. And by 2030, urban aviation could be a major mode of getting from A to B.
But all of this raises a fundamental question: Why now? Why, in the late spring of 2018, are flying cars suddenly ready for prime time? What is it about this particular moment in history that has turned one of our oldest science fiction fantasies into our latest reality?
After all, weâve been dreaming of Blade Runner hover cars and Back to the Future DeLorean DMC-12s for millennia. Vehicles capable of flight date back to the âflying chariotsâ in the Ramayana, an eleventh-century Hindu text. Even the more modern incarnationsâthat is, ones built around the internal combustion engineâhave been around for a while. The 1917 Curtiss Autoplane, the 1937 Arrowbile, the 1946 Airphibian, the list goes on. There are over a hundred different patents on file in the US for âroadable aircraft.â A handful have flown. Most have not. None have delivered on the promise of The Jetsons.
In fact, our ire at this lack of delivery has become a meme unto itself. At the turn of the last century, in a now famous IBM commercial, comedian Avery Brooks asked: âItâs the year 2000, but where are the flying cars? I was promised flying cars. I donât see any flying cars. Why? Why? Why?â In 2011, in his âWhat Happened to the Future?â manifesto, investor Peter Thiel echoed this concern, writing: âWe wanted flying cars, instead we got 140 characters.â
Yet, as should be clear by now, the wait is over. The Flying Cars Are Here. And the infrastructureâs coming fast. While we were sipping our lattes and checking our Instagram, science fiction became science fact. And this brings us back to our initial question: Why now?
The answer, in a word: Convergence.
Converging Technology
If you want to understand convergence, it helps to start at the beginning. In our earlier books, Abundance and BOLD, we introduced the notion of exponentially accelerating technology; that is, any technology that doubles in power while dropping in price on a regular basis. Mooreâs Law is the classic example. In 1965, Intel founder Gordon Moore noticed that the number of transistors on an integrated circuit had been doubling every eighteen months. This meant every year-and-a-half computers got twice as powerful, yet their cost stayed the same.
Moore thought this was pretty astounding. He predicted this trend might last a few more years, maybe five, possibly ten. Well, itâs been twenty, forty, going on sixty years. Mooreâs Law is the reason the smartphone in your pocket is a thousand times smaller, a thousand times cheaper, and a million times more powerful than a supercomputer from the 1970s.
And itâs not slowing down.
Despite reports that we are approaching the heat death of Mooreâs Lawâwhich weâll address in the next chapterâin 2023 the average thousand-dollar laptop will have the same computing power as a human brain (roughly 1016 cycles per second). Twenty-five years after that, that same average laptop will have the power of all the human brains currently on Earth.
More critically, itâs not just integrated circuits that are progressing at this rate. In the 1990s, Ray Kurzweil, the director of engineering at Google and Peterâs cofounding partner in Singularity University, discovered that once a technology becomes digitalâthat is, once it can be programmed in the ones and zeroes of computer codeâit hops on the back of Mooreâs Law and begins accelerating exponentially.
In simple terms, we use our new computers to design even faster new computers, and this creates a positive feedback loop that further accelerates our accelerationâwhat Kurzweil calls the âLaw of Accelerating Returns.â The technologies now accelerating at this rate include some of the most potent innovations we have yet dreamed up: quantum computers, artificial intelligence, robotics, nanotechnology, biotechnology, material science, networks, sensors, 3-D printing, augmented reality, virtual reality, blockchain, and more.
But all of this progress, however radical it may seem, is actually old news. The new news is that formerly independent waves of exponentially accelerating technology are beginning to converge with other independent waves of exponentially accelerating technology. For example, the speed of drug development is accelerating, not only because biotechnology is progressing at an exponential rate, but because artificial intelligence, quantum computing, and a couple other exponentials are converging on the field. In other words, these waves are starting to overlap, stacking atop one another, producing tsunami-sized behemoths that threaten to wash away most everything in their path.
When a new innovation creates a new market and washes away an existing one, we use the term âdisruptive innovationâ to describe it. When silicon chips replaced vacuum tubes at the beginning of the digital age, this was a disruptive innovation. Yet, as exponential technologies converge, their potential for disruption increases in scale. Solitary exponentials disrupt products, services, and marketsâlike when Netflix ate Blockbuster for lunchâwhile convergent exponentials wash away products, services, and markets, as well as the structures that support them.
But weâre getting ahead of ourselves. The rest of this book is devoted to these forces and their rapid and revolutionary impact. Before we dive deeper into that tale, letâs first examine convergence through a more manageable lens, returning to our initial question about flying cars: Why now?
To answer that, letâs examine the three basic requirements any Uber eVTOL will have to meet: safety, noise, and price. Helicopters, which are the closest model anyone has for a flying car, have been around for nearly eighty yearsâIgor Sikorsky built the worldâs first one in 1939âyet they canât come close to satisfying these requirements. Besides being loud and expensive, they have that bad habit of falling out of the sky. So why are Bell, Uber, Airbus, Boeing, and Embraerâjust to name a fewâbringing aerial taxis to market today?
Once again: Convergence.
Helicopters are loud and dangerous because they use a single gargantuan rotor to generate lift. Unfortunately, the tip-speed of that single rotor produces exactly the right thud-thud-thud frequency to annoy pretty much anyone with ears. And theyâre dangerous because, if that rotor fails, well, gravity plays for keeps.
Now imagine, instead of one main rotor overhead, a bunch of smaller rotorsâlike a row of small fans beneath a planeâs wingâwhose combination generates enough lift to fly, but pumps out a lot less noise. Better yet, imagine if this multi-rotor system could fail gracefully, landing safely even if a couple rotors stopped working at once. Add to this design a single wing that enables speeds of 150 mph or more. All great ideas, except, thanks to their terrible power-to-weight ratios, gasoline-powered engines make none of this possible.
Enter distributed electric propulsion, or DEP for short.
Over the past decade, a surge in demand for commercial and military drones has pushed roboticists (and drones are just flying robots) to envision a new kind of electromagnetic motor: extremely light, stealthily quiet, and capable of carrying heavy loads. To design that motor, engineers relied on a trilogy of converging techs: first, machine learning advances that allowed them to run enormously complicated flight simulations, then materials science breakthroughs that let them create parts both light enough for flying and durable enough for safety, and last, new manufacturing techniquesâ3-D printingâthat can create these motors and rotors at any scale. And talk about functionality: These electric engines are 95 percent efficient compared to gasolineâs 28 percent.
But flying a DEP system is another story. Adjusting a dozen motors in microsecond intervals is beyond a human pilotâs skill. DEP systems are âfly-by-wireââthat is, computer controlled. And what produces that level of control? Another swarm of converging technologies.
First, an AI revolution gave us the computational processing horsepower to take in an ungodly amount of data, make sense of it in microseconds, and manipulate a multitude of electric motors and aircraft control surfaces accordingly, in real time. Second, to sweep in all that data, you need to replace the pilotâs eyes and ears with sensors capable of processing gigabits of information at once. That means GPS, LIDAR, radar, an advanced visual imaging suite, and a plethora of microscopic accelerometersâmany of which are the dividends of a decade of smartphone wars.
Finally, youâll need batt...
