First off I’d say security is the biggest.. With the “Internet of Things” and many more devices becoming “SMART” device the need will only grow. This is also evident in network breaches we hear about in the news. So security is a major plus. Some programming languages have slow been dropping off over the years so there is a constant need to learn new ones. As new hardware comes around these could change the direction much sooner than later. Technology is moving so much faster today. What took 10 years to develop years ago may now take a matter of months.
