Fumes requiring ventilation, molten metal, temperatures that can sear flesh or melt most plastics, the appearance if not fact of irreversability (and in fact, it's not hard to do damage to the circuit board that is hard to repair). Like bicycling, cooking, and a host of other activities, it's a very productive and useful skill to have, and seems to those who have the skill to be trivial to learn - but to those without the skill, it's intimidating (partly because there is some potential for damage if it's done wrong).
