And an important quote:
"Over the long run, technological advance creates new goods and services, raises national income, and increases the demand for labor throughout the economy. However, it is important to note that these changes can create winners and losers—some workers will lack the skills to transition to new jobs. Recent technological advance has increased the demand for highly skilled workers, whose labor is a complement to the new technology, but the new technology has replaced the labor of some less-skilled workers. Therefore, it's important that workers invest in their human capital and continue to improve their skills throughout their working years. "
