Lorenzoid said "Don't confuse what goes on in dive shops to what goes on on SB",
That is absolutely true.
Posters on SB probably do not even make up a fraction of one percent of all divers world wide.
The dive shop world and the dive internet world are two separate parallel universes.
We debate and have a lot of great ideas. Unfortunately the dive shops are the ones more in charge of meeting the new diving public as the first point of contact, and in my opinion many do a pretty miserable job of promoting and selling diving to new prospective candidates. Some of this has to do with no marketing plans other than standing behind the counter and waiting for people to come in.
There are also many cultural changes at play as to the fate of diving.
When diving first became known we were coming out of WWII, there was a lot of growth in many areas of society, there were a lot of new things being invented, new sports/activities, new music, new cars, new social styles. In almost every area of life there was something new and exciting.
Diving was part of that.
All the gear choices and other things we think are making diving unattractive to the youth I don't think have anything to do with it. They're not interested way before they ever learn about such things, they're not getting started in the first place.
Back in the 50's and 60's it was an analog world. There were only 12 channels on TV (if you were lucky), no computers, no smart phones, no video games, and a lot of other things that weren't invented yet. It was a simpler time. Kids actually played outside and took part in actual reality, not virtual reality.
These days there are too many distractions. They are also finding out that life long patterns of behavior are encoded in children very young. What children do in their first five to eight years of life has a huge impact on their behavioral and social patterns later.
All these factors combined are what's killing not only diving but a lot of other sports. Kids are not learning how to be physical at a young age. I see so many restrictions placed on children now for play, at school, in the front yard, etc. for fear of injury or abduction or liability.
Back when I was a kid we had freedom and full reign to play outside as much as we wanted, as long as our homework was done.
We didn't have a TV in my house so all I did was play outside building forts, riding our bikes off home made jumps, breaking bones, etc. kids aren't allowed to do a quarter of the stuff we did and so they have no primer, no encoding for adventure or activity.
That's my take.
