When choosing your career it's wise to select those that will be in high demand and to avoid those that may become obsolete. Revolutions in technology are causing rapid, almost un-predictable change in career demand. However, some long-term trends such as an increase in population of older people are more predictable. Changes in technology can obsolete your job causing you to be laid off, downsized, right sized, and just plain inconvenienced.
Many jobs now come into being for a few years and then disappear.
The key to selecting your future career is to understand the long-term trends that are taking place. Home healthcare and nursing homes are just two areas to benefit. By linking everyone's home directly to manufacturers and service providers the entire infrastructure and sales channel will change. Anyone who makes his or her living as a middleman had better change careers or become expert at adding unique value. The middleman in many business transactions will gradually disappear largely as a result of technology and competition.
