Good examples of this are automated customer "service" and "self"-driving technologies. The latter has done nothing but spin its wheels by burning off R&D dollars and time while killing people along the way. Eventually, people will realize that a much better goal is to simply assist drivers in more effective ways and to pour the resources into better urban design and non-automotive transportation. Unfortunately, that's happening not because of realization of this but because of the realization that self-driving is a pipe dream of being able to solve intractible societal and technological problems.
