I wish these disclaimers went upfront, the way a newspaper by-line would have been. I've never engaged much with Fortune anyway, but this makes me much less interested in doing so moving forward--if I wanted to know what an LLM thought of airport lounge crowding, I could ask one myself.
Cars, dogs, and water.
These are the big three common things that children interact with regularly that can, and will, cause irreparable harm or death with functionally no warning and virtually instantaneously. Kids also don't have the experience or the intuition to figure out if a situation is dangerous; cars move too fast, dogs are too hard to read, and water danger is hard to grasp even for adults (the number of people, including grown adults, I've seen panic and had to get pulled out after gleefully jumping into water where it turns out they can't reliably touch the bottom is fairly high).
The first two require some strictness (i.e. being very clear about rules like never going near a road without an adult, and never hitting a dog or pulling it's ears), but water basically requires regular swimming lessons from qualified instructors. It's something I wish happened earlier, and that more families had easy access to.
