Photos are for more artistic uses than being artwork themselves. They are also for taking pictures of interesting textures that can be used to texture a model, backgrounds to use behind figures, or as references for making models. Just to name three of the more obvious uses.
On a non-art front, I also take pictures as "notes" from books (instead of spending hours and hours and reams of paper writing stuff down), or to document something that happened so there'd be no question exactly how something looked at a specific point in time, or to take pictures of friends/relatives/pets for memory books. (No one cares if the picture is artwork, or even halfway good, if you have the only picture of grandma that there is.)
With the digital, I can also take a picture to look somewhere that I cannot see, and then look at it to see what's there. (Is the dead mouse under the bed? No, keep looking for it. Is there a skunk under the workbench? No, whew, it moved on. Did the hen lay eggs under the hen house again? Only one, and I'm not kneeling down in the mud to get it. Is the cat hiding behind the towels? Aha, there she is.)
As for Spring of 2000 being quite a while ago.....I got my first camera in the 1960s.
