What? This comment reads to me that you want a homogenous society... The people who do great things take big risks. Shit happens. This is a thread for startups, where many people eschew the "safe" corporate jobs in order to create or do something that many people don't think are possible.
You're reading about an accident, and then assuming the amount of risk involved without knowing anything about the sport. Accidents happen all the time, in all sorts of ways. It's very possible to do something like this and have a large safety margin, as has been shown by his 24yr history of doing it. Someone who is this experienced at what they do, in a dangerous seeming sport, will be very well aware of possible mistakes, and how to mitigate them. I personally think teaching your child to be "safe" and not take "risks" is kind of stupid. I'd much rather teach my child to learn how to push the limits intelligently, and see what in this world is possible.
> Should we strive for an equal society? As such, shouldn't all children be born with equally (or minimally) committed parents?
I wasn't sure what you meant by "equal society," everyones different, the only way to get "equal" where all children have "equally" committed parents, would be quite homogenous.
The main point I think I'll reiterate, is that yes, you are assuming the amount of risk this person took. The amount of risk involved goes down the more you know about something. This person definitely knows more than you about the sport of cave diving, and can better judge the amount of risk involved. I think that's all I'm trying to say. You can do something that seems dangerous to outsiders, quite safely.
And I also think that lessons from one sport, or activity, apply to other areas of life.
I'm still not sure, but yes - a child shouldn't be exposed to unusual, or high levels of risk due to the "attitude of the parent".
This person knows more than I do about diving, but not necessarily about risk; A doctor who studies lung cancer might know more about the risks of smoking than a life-long smoker.
