Indeed, the concept behind Tacocopter is very simple, and very American: You order tacos on your smartphone and also beam in your GPS location information. Your order — and your location — are transmitted to an unmanned drone helicopter (grounded, near the kitchen where the tacos are made), and the tacocopter is then sent out with your food to find you and deliver your tacos to wherever you’re standing.
The problem? Regulation.
The U.S. government is single-handedly preventing you from ordering a taco and having it delivered to you by a totally sweet pilot-less helicopter.
Whether you think the Tacocopter is awesome or silly, this points to a genuine problem. Government regulation has grown significantly over the past 50 (or 100) years, and it is getting in the way of innovation, slowing down the pace at which we discover things that could make our lives better. It seems particularly harmful in areas such as medicine, or energy, but since innovation is about discovering the unknown, there is no way to tell what we are missing.
Lawmakers need to keep the longer term in mind when regulating us. Otherwise we risk staying in the great stagnation for quite a while.
