Instructors and certifications are not the crux of the scuba industry, I really don't understand why people consider them so important.
Destination dive sites are where the money is, they create the most jobs and create a huge demand, local instructors in the US are not even on the map of the scuba industry as a whole.
I think this is the crux of a lot of discussions that have been going around SB recently.
Local diving, the sport we think of when we talk about SCUBA, is probably dying. It was never huge to begin with, it is too expensive for most people to get into, and in most of North America it is highly seasonal due to weather. People don't want to struggle into heavy gear, schlepp it to the water, and freeze their asses off in cold water. They don't know anybody who dives locally and aren't interested in spending hours on FB looking for a dive buddy. They aren't getting into the hobby, which is hurting LDSs and down the line.
On the other hand, vacation diving in clear, warm, tropical water seems to be doing fine. There are enough people willing to spend the money as part of a vacation (Just put it on the air miles card!) and get an adequate level of training that they can (mostly) go dive a few times once or twice a year in warm clear water without dying.
The canny dive shops are adapting to this by offering partial training, referrals, and organizing tours to those warm, clear waters. They also cater to the few remaining locals and the people who need to go dive more often, but we are not the majority.
Is there an instructor crisis? Yes, if you are trying to make a living teaching local students in cold, dark waters
Is there a diver skills crisis? Yes, if people who have only learned to dive in warm clear water with a legally mandated guide are now trying to dive in cold, dark, current influenced waters.
Is there a LDS crisis? yes, if you are only really selling to local cold water divers, especially in cold climates and think the twice a year on vacation diver is a waste of your time.
Just as the industry is adapting to customer demand, so to do our expectations need to adapt. It's going to get harder to find boats and buddies and in some cases air fills. The next generation of scuba diver is not going to be like us, and isn't going to want to do the things we find valuable. Like it or not, we are the dinosaurs here, and blaming the end times on the mammals will not preserve the species.
