In the fall of 2019, Google told the world it had reached “quantum supremacy.”
It was a significant scientific milestone that some compared to the first flight at Kitty Hawk. Harnessing the mysterious powers of quantum mechanics, Google had built a computer that needed only three minutes and 20 seconds to perform a calculation that normal computers couldn’t complete in 10,000 years.
But more than two years after Google’s announcement, the world is still waiting for a quantum computer that actually does something useful. And it will most likely wait much longer. The world is also waiting for self-driving cars, flying cars, advanced artificial intelligence and brain implants that will let you control your computing devices using nothing but your thoughts.
Silicon Valley’s hype machine has long been accused of churning ahead of reality. But in recent years, the tech industry’s critics have noticed that its biggest promises — the ideas that really could change the world — seem further and further on the horizon. The great wealth generated by the industry in recent years has generally been thanks to ideas, like the iPhone and mobile apps, that arrived years ago.
Have the big thinkers of tech lost their mojo?
The answer, those big thinkers are quick to respond, is absolutely not. But the projects they are tackling are far more difficult than building a new app or disrupting another aging industry. And if you look around, the tools that have helped you cope with almost two years of a pandemic — the home computers, the videoconferencing services and Wi-Fi, even the technology that aided researchers in the development of vaccines — have shown the industry hasn’t exactly lost a step.
