Nearly two years ago, I wrote that the phenomenal economic and social potential of commercial drones, more properly called unmanned aircraft systems (UAS), was being stymied by a slow-moving Federal Aviation Administration. Pending agency action, commercial uses for drones were effectively banned. (Hobbyist drone users are free to play, so long as they stay below 400 feet and away from airports.)

In 2012, Congress gave the FAA until 2015 to develop rules for military, commercial, and privately-owned drones to operate in U.S. airspace. In fact, the FAA had originally promised the rules by 2011, but it proceeded to miss every deadline it set for itself, as well as those established by Congress.

Well, 2015 has now arrived, and last month, investors, entrepreneurs, and other drone supporters gave two cheers when the agency at last released a draft of its proposed regulations.

In many industries, drones are poised to generate what Paul Nunes and I call Big Bang Disruptions, with the FAA itself estimating $100 billion in new business growth. Drones could revolutionize everything from natural resource protection, agriculture, emergency services, aerial photography, filmmaking, and delivery.

The draft rules would at last permit such commercial applications, with significant but not unmanageable restrictions. Drone operators will be regularly required, for example, to pass a written test, but won’t, as rumored, need to obtain a pilot’s license. The draft also leaves open the possibility of less restrictive rules for the smallest and lightest micro-drones, which pose little risk in the air or on the ground. “Technology is advancing at an unprecedented pace and this milestone allows federal regulations and the use of our national airspace to evolve to safely accommodate innovation,” Transportation Secretary Anthony Foxx said in a press release that accompanied the announcement.

When it comes to flying electronic devices weighing up to 55 pounds, safety is an essential requirement. But are the delays justified? The short answer is no. The proposed rules are vague and incomplete, where they could easily be straightforward and even obvious. Special rules for micro-drones should have come first, not just hinted at last. And an unnecessarily restrictive requirement that all drone operation require continual “line of sight” visibility and daylight-only operation means that some of the most high-potential applications, including local delivery services and nighttime agricultural monitoring, are still banned.

The FAA’s continued delays, in short, have little if anything to do with assuring the safety of U.S. airspace. They have, instead, everything to do with bureaucracy and interest group politics. In Washington, business as usual.

In stark contrast, the last four years have seen continued improvement in drone technology, much of which cannot be put to use. Like many of the Big Bang Disruptors we track, drones are piggybacking off the smartphone revolution, which has built efficient global markets for increasingly cheap off-the shelf cameras, processors, gyroscopes, accelerometers, and software that can be embedded in UAS. (Many use smartphones and tablets as their controllers.)

According to the Consumer Electronics Association, drone shipments will increase from 250,000 units in 2014 to nearly a million by 2018. And that’s for a technology that is, and will remain, largely illegal. Because even with the publication of the draft rules, the FAA’s ban is far from over. Following time-honored administrative traditions, the FAA’s proposal will now go through a protracted comment period, public hearings, and further closed-door discussions with stakeholders. Most observers estimate it will be another two years before final rules are even approved.

Indeed, the FAA wasn’t actually prepared to release the draft rules when it did, but in a snafu that highlights the underlying problem here, the agency’s hand was forced when industry watchers discovered a report analyzing the economics of the proposed rules inadvertently posted on the FAA’s website.

The cat out of the bag, the FAA hastily convened a Sunday press conference to announce the draft rules, further eroding any remaining confidence that the agency’s high-minded rhetoric about ensuring public safety is anything more than an excuse.

As the long-running drone rulemaking painfully highlights, the mismatch between rapidly-evolving disruptive innovations and the slow, deliberative model for expert agencies overseeing new industries has reached its breaking point–and then some. The FAA’s processes, like those of most federal and state administrative agencies, haven’t really changed since the days of the railroad and telegraphs, which marked the beginning of our “modern” administrative state.

The FAA’s bumbling is hardly unique. Across the technology sector, more and more start-ups are coming into conflict with an expanding range of regulators whose inner workings are intentionally secretive, and which seem designed to slow down precisely when they are pressured to speed up.

The Internet of Things, for example, is being stymied by the Federal Trade Commission’s valid but vague concerns about privacy protections, while crowdfunding and other innovative forms of finance await overdue rules from the Security and Exchange Commission. The Food and Drug Administration, meanwhile, has tortured home genetic testing services with years of delay and conflicting requirements. Taxicab, limousine, and hotel commissions under the thumb of incumbent providers are holding back a tidal wave of “sharing economy” services, which have introduced technological innovations the incumbents have little incentive to build. And state and federal departments of transportation have barely started to think about the pros and cons of self-driving vehicles, which are poised to revolutionize automotive and related industries.

The causes vary for this epidemic of counter-productive interference, which is threatening a long and successful policy, at least in the U.S., of what George Mason University’s Adam Thierer calls “permissionless innovation.” One problem is that regulatory agencies are institutionally, and perhaps even legally, unable to innovate their processes. Many agencies have so far been untouched by the digital revolution and have little, if any, expertise to apply.

Self-interest also plays a big part in the stonewalling, as bureaucrats feel threatened by technologies that allow consumers to rate and otherwise discipline companies, suggesting better and cheaper alternatives to corruptible human regulators. All too often, as well, regulated incumbents and other stakeholders are encouraging the delays and obstacles rather than retooling themselves to compete with technology-driven disruptors.

Entrepreneurs can’t wait for governments to catch up to the 21st century. Indeed, some countries are making inroads, not by inventing better technology, but by innovating their regulatory systems. Both the U.K. and Canada, for example, have already established rules for some commercial drone activities, giving their start-ups the opportunity to develop new applications and businesses while U.S. entrepreneurs twiddle their thumbs.

In an increasingly global market both for consumers and entrepreneurial talent, even a slightly more efficient approach to regulating can make all the difference. As our research shows, better and cheaper innovations often generate “winner take all” markets. So countries that unshackle their innovators first may capture the momentum that drives future innovation and investment.

Today, the FAA’s continued haplessness may doom the enormous potential of an inchoate U.S. commercial drone industry. But tomorrow, without Big Bang reform for our administrative state, the same fate may befall entrepreneurs working in 3D printing, health and fitness tracking devices, smart energy and transportation, and pretty much every other industry where Big Bang Disruption is imminent.

Which is pretty much all of them.
