Of course we're not going to see a complete end to productivity. Just as there are still a significant number of people who buy trucks to haul produce, products and tools, there will continue to be professional programmers, writers, accountants, videographers and others with access to whatever tools they need to do their job. But I worry that this group, just like farmers and skilled craft people, will become a smaller and smaller segment of our population. And I'm especially worried that an increasing number of them will be working from outside the United States at lower wages.
