I'm in my 60's. I not only use computers, but program them.
Speaking from my own experience, I was interested in photography at an early age, but could not get serious about it until my 20's due to the cost. These days, younger folk are satisfied with their smartphone cameras, which are much better than anything I had when I was their age. This forum is for those who are serious about photography and want to improve. That takes time and maturity and it's not for everybody. The ones who gravitate to this forum will not be those who count "likes" on Instagram and Facebook. They'll be the ones who look critically at their photos and wonder how they could be better.
