Technology obsoletes skill in many cases, and that plain and simply stinks. Sometimes it feels there is more emphasis on gathering the right equipment then actually perfecting the trade. But you have to if you want to stay on top of the trade. If your a hobbyist, well, you can emerge from a purist shell anytime you want. As an artist, being a purist may help you more than hurt.
Technology does sometimes obsolete a skill. That does not "stink." That simply forces the art and craft forward and upward.
Carpenters once had to cut their own nails. That was a skill. Then they developed a machine that could cut nails more quickly, more cheaply. When a machine can do a task as well or better than a human, that task is no longer a "skill," and certainly not an "art." If a machine can do it, it becomes mere drudgery--letting a machine do it frees the human to elevate his craft. The carpenter who no longer has to cut his own nails can spend more time with the more creative aspects of his craft.
Before autofocusing, a sports photographer had to spend years perfecting the ability to follow-focus a 300mm f/2.8 lens on a football, hockey, or basketball player. Yes, that was a skill, and an enviable one--some people never had the DNA to develop that kind of dexterity--it was kind of an athleticism that not everyone could attain even with great practice.
But a machine now does it with greater success than the best sports photographers ever attained, which frees them to pursue the higher elements of art and craft.
