My dad recently asked me what I think is the next big thing in technology: what will fundamentally change the way people live their lives? This article pretty well sums up many of my thoughts on the matter.
I don't think "the singularity" will happen as soon or in the way that some people think, but Artificial Intelligence is going to have a big impact on a variety of industries, and the market will have to adapt. In the relative near-term, I expect robots will take on most of the work in moving objects and people from place to place: big rig trucking, public transit, taxi cabs, doorstep deliveries, and warehouse loading will probably be done almost entirely by machines a few decades from now.
This effect is nothing new. Factory production has moved people away from most of the menial labor they used to do, and into more of an overseer role. As a result, we enjoy many conveniences that would have been economically unfeasible otherwise. Personal computers and other office machinery has largely replaced most secretarial work, and instead we have to train every office worker how to use these machines. So far, the job market has always adapted to these new realities, and things are generally better for the introduction of these new technologies.
But at some point, if we don't run into some kind of apocalypse first, we will likely hit a point where the market can't keep up so easily: we'll hit a road-bump much like the farm crisis of the 1920s, when technology causes a huge shift in the balance of supply and demand. And, at least in the short term, we will need to find similar solutions to those which eased the effects of the farm crisis: an eco-political model that's less focused on the merit of the work that people do. Failure to do so would result in an enormous political upheaval: we don't really care all that much if rich people become obscenely rich, but if they end up owning all the means of production in the world with almost no reliance on the lower class, a traditional free-market approach will naturally trend toward a horrible oppression of the poor.
But hopefully that's a long way off.
