How Corruption Is Strangling U.S. Innovation

Posted on by

One of the prime drivers of economic growth inside America over the past century has been disruptive innovation; yet the phenomenon that Lessig describes is increasingly being used by large incumbent firms as a mechanism to stave off the process. Given how hard it can be to survive a disruptive challenge, and how effective lobbying has proven in stopping it, it’s no wonder that incumbent firms take this route so often.

Netflix. Uber. Airbnb. Tesla. Fisker. Most economies would kill to have a set of innovators such as these. And yet at every turn, these companies are running headlong into regulation (or lack thereof) that seems designed to benefit incumbents like NADA and Comcast — regulation that, for some strange reason, policy makers seem extremely reticent to change if it results in upsetting incumbents.

Operating at telecom wavelengths (i.e., the range commonly used in fiber-optic communications), the new device is completely scalable, from near-infrared to terahertz wavelengths, and simple to manufacture. The results have been published online in the journal Nano Letters.

“In the future we can potentially replace all the bulk components in the majority of optical systems with just flat surfaces,” says lead author Francesco Aieta, a visiting graduate student from the Università Politecnica delle Marche in Italy. “It certainly captures the imagination.”

 

Steve Jobs Solved the Innovator’s Dilemma

By taking this approach, Apple bent all the rules of disruption. To disrupt yourself, for example, Professor Christensen’s research would typically prescribe setting up a separate company that eventually goes on to defeat the parent. It’s incredibly hard to do this successfully; Dayton Dry Goods pulled it off with Target. IBM managed to do it with the transition from mainframes to PCs, by firewalling the businesses in entirely different geographies. Either way, the number of companies that have successfully managed to do it is a very, very short list. And yet Apple’s doing it to itself right now with the utmost of ease. Here’s new CEO Tim Cook, on the iPad disrupting the Mac business: “Yes, I think there is some cannibalization… the iPad team works on making their product the best. Same with the Mac team.” It’s almost unheard of to be able to manage disruption like this.
