[sorry I can't resist, this is not the first one of these I've read lately]
Do divers not know how to orally inflate a BC anymore???? What is going on with divers panicking or dieing because of one little button not working!?
I think if you ask any diver if they know how to orally inflate a BCD the immediate answer would be a resounding yes. However people who are inexperienced or unprepared for an incident are rarely capable of clear logical thinking.
A new diver descending to depth attempts to inflate the BCD, notices nothing happens, confused they try again, still nothing. Now they are descending faster then they want and are unable to stop the descent. They start panicking, kicking as hard as they can for the perceived safety zone the surface. What would be a minor annoyance to a prepared experienced diver turns into a very serious incident.
There are too many divers who breeze through courses, who do the required skill in the pool or in a controlled supervised OW dive who take the risks of diving for granted and never think about or practice what am I going to do if ____ happens.
In addition there are far too many divers who can't be bothered to do a proper buddy or even personal gear check to make sure your hose is connected and BCD working before jumping in the water.
While it is great that a lot of people are taking up diving to see the underwater world, there are many people who do not take it seriously enough and who despite holding a valid C-card probably should not dive.
