This photo was taken on the Swedish island of Gotland in the summer of 2013. Lighthouses are symbols for guidance. They existed in the Mediterranean as early as antiquity. At the time, the lighthouse of Alexandria, approximately 150 meters tall, was one of the Seven Wonders of the World.
However, it is hard to overlook the fact that their importance has dwindled in the last decades. A substantial number of lighthouses has given way to satellite navigation and electronic devices. Fortunately, there will be enough lighthouses left for us to visit and admire for many years to come.
Similarly to the lighthouses, formerly ubiquitous technologies in IT lose importance without disappearing altogether. That's why it is essential to stay up to date on the latest technologies so that we can implement them whenever and as soon as they prove useful and advantageous.
The only constant in IT is change. That change is brought about by a steady advent of new technologies, some of which turn out a flash in the pan, while others become great successes.
