The impact of technology on the job market

After reading several articles related to how the jobs will be in the short and mid-term term, I see that our best bet is on learning new technology. We all have heard, read or seen that companies are changing, they are becoming less protective of employees. Therefore, employees are changing too; they are more focused on their career progression within or without their current employer. From an HR perspective, this change means a big change in terms of talent management, total compensation, and so on.
Currently, it is up to the employees (interested in getting promotions) to expand their skill set either taking advantage of employer sponsored professional development or self-paid external education. The tenure privileges era is gone. Actually, even people who are not looking forward to growing their career because they are already satisfied with their current level will need to work on their skill set just to secure a paycheck since technology is substituting some of those jobs; for example, people who were laid off from a supermarket to be replaced by a man-made cashier. In reality, this technological trend will create more knowledge demanding but better paid jobs. At the end, the necessary specialization and competition that we have to face will help us to improve our quality of life and as a result our communities.
