Said from your safe little bubble. Dangerous is "I might misstep by half an inch and orphan the children."
The college educated computer workers who post here haven't experienced danger since climbing trees as children. And certainly don't experience danger professionally.
Roofing a house is dangerous. Delivering Pizza is dangerous.
Picking between State U vs Private U? Choosing between Python and Ruby? Choosing between iOS vs Android for your initial deployment? Choosing VC A over VC B? Telling your Boss he's wrong? Calling any of that dangerous is an insult to people who face real danger daily.

Speaking as a college educated computer worker who posts here, I suspect that you might not have a clue. I spent a lot of last summer welding heavy metal, I am no stranger to hard-hats, safety boots and building sites.

Is a bit like going to a gym where they pay you.
Be very careful of stereotypes, especially among groups that are well known for idiosyncrasies, which at the last count is pretty much all the groups.
Did you really think you needed to point out that I might be making a sweeping generalization about tens of thousands of users? I'm glad you decided to share.
There's a difference between incorrect and dangerous.
