But a solution is not to ban the use of fire and limit it to just a few practitioners. Rather, it's teaching responsible fire use at a tender age of maybe seven years old. It's called cooking class, by the way, and sharing the recipes and so on. And of course, hiring professional fire-making people to test every tunnel, right, to improve our building inspection rules and so on. And so the society learned to live with fire, and that's how civilization is built.
