We love the idea of autonomous trucks. And it looks like Volvo is set to dominate this innovative space. But it does raise an interesting question. Once drivers are no longer needed, where do those people find employment? On the docks loading the trucks...unlikely, since the next obvious innovation is autonomous loaders and in computer controlled warehouses. I for one welcome our self-driving overlords if only for the reason that there will be fewer accidents on major highways - and maybe, goods will be shipped in the midnight hours. But it should give everyone pause. Exactly how will a growing population find employment in a world run by machines?
