The Future Approaches, and it's Scary

CNN article

The article itself isn't really that scary, it's actually kind of funny and cool to imagine. In Japan, where a decreasing amount of the population is actually part of the workforce, a store has "hired" a robot employee, that functions smoothly and can crudely interact with people.
The article states that, though this one can't speak, future ones will be able to do so smoothly and without hitch. They will be able to perform all the simple tasks required in running a store: stocking shelves, checking out groceries, etc. In the future, the article also states, robots may be more a cheaper alternative to such jobs as fast food restaurants; rather than having to pay employees, companies could just install these robots to do the job for them.
It sounds cool at a glance. It's the kind of thing we always see in movies, the kind of thing we've always imagined for the future, and for a country like Japan it's even necessary.
Upon further consideration, the author can see a process called "creative destruction": when a new technology is created to more efficiently solve a problem, it takes away jobs, because having people manually doing what robots can do is financially illogical.
Many people, especially minimally-skilled people like high school and college students, rely on these jobs to help pay the bills until they can acquire the skills for more advanced and specialized jobs. Some people who never have any formal education rely on them for much longer, maybe their entire lives. It is not ideal, but it is a fact of life.
I am not personally against progress like this. Perhaps because the lowest jobs are occupied, there will be more motivation to become educated and excel to higher jobs, safe from the threat of a mechanized takeover.
Or perhaps they will cause so large a dent in jobs that unemployment rates skyrocket, and no one can afford the products or services produced, causing economic collapse.
Either way, society and economics are changing, evolving. That is a certainty. The only uncertainty is: what they are evolving into?
