<i>The hoverboard industry in Shentzen has collapsed.</i><p>This is a classic &quot;market for lemons&quot; event. People might say that there is a market for safe electric skateboards, but since consumers have no way of identifying a safe one and all the safety markings are forged, they&#x27;re not going to buy one at all.<p>People need to bear this in mind when asking for deregulation in general. Sometimes it&#x27;s necessary to remove the actively dangerous vendors from a market.<p>(When life gives you flammable explosive lemons, what would Cave Johnson do?)<p>Edit: arguably this is already happening in the consumer IoT market. The default assumption is that a product will spy on you, be uninteroperable, insecure, and vulnerable to remote-bricking by the manufacturer. Each individual product has to swim upstream this current of skepticism. Hence the joke about at least the exploding skateboards not being internet-connected.
