> Most people have no idea how to hunt, make a fire, or grow food

That's a bizarre claim, confidently stated.

Of course I can make a fire, cook and my own food. You can, too. When it comes to hunting, skinning and the cutting of animals, that takes a bit more practice but anyone can manage something even if the result isn't pretty.

If stores ran out of food we would have devastating problems but because of specialization, just because we live in cities now you simply can't go out hunting even if you wanted to. Plus there is probably much more pressing problems to take care of, such as the lack of water and fuel.

If most people actually couldn't cook their own food, should they need, that would be a huge problem. Which makes the comparison with IT apt.

> Most people have no idea how to hunt, make a fire, or grow food. If all grocery stores and restaurants run out of food for a long enough time people will starve.

I doubt people would starve. It's trivial to figure out the hunting and fire part in enough time that that won't happen. That said, I think a lot of people will die, but it will be as a result of competition for resources.

>If all grocery stores and restaurants run out of food for a long enough time people will starve. This isn't a problem in practice though...

I fail to see how this isn't a problem? Grid failures happen? So do wars and natural disasters which can cause grids and supply chains to fail.

In Star Trek they just 3D printed everything via light.

Ok, poof. Now everyone knows how to hunt, farm, and cook.

What problem does this solve? In the event of breakdown of society there is nowhere near enough game or arable land near, for example, New York City to prevent mass starvation if the supply chain breaks down totally.

This is a common prepper trope, but it doesn't make any sense.

The actual valuable skill is trade connections and community. A group of people you know and trust, and the ability to reach out and form mini supply chains.
