It may be unpopular and out-of-date to say-but I do not think that a scientific result which gives us a better understanding of the world and makes it more harmonious in our eyes should be held in lower esteem than, say, an invention which reduces the cost of paving roads, or improves household plumbing.
It adds up, but I deem it all necessary, even the camera gear. I enjoy photographing the otherworldly colors and shapes presented in the convoluted depths of slot canyons and the prehistoric artwork preserved in their alcoves.
