So-So Artificial Intelligence

A lot of the conversation about the future of AI and automation focuses on the AGI endgame ("will humans still work when artificial general intelligence can do everything?"). But there are more interesting, tractable, and concrete questions to answer about the effects of "narrow," task-specific AI that looks more or less like what we have today. In the near future, we can expect more advanced robotics, autonomous cars, customer service chatbots, and other applications powered by such narrow AI to take over certain tasks from humans. Should we be optimistic about labor in the next 10-50 years, when parts of industries will be automated by narrow AI? What early signs of those trends should we be concerned about now?
