No. It is so that they don't have deal with developers tricks and misdirections and intentionally misleading uis and so on. It is also so that they are not required to learn tons of obscure and otherwise useless knowledge to function reasonably.

None of that makes them stupid. Just like, when I am in grocery store I can be sure all food there is reasonably safe, even if I don't know anything about them. I am not expected to research them all personally for dangerous substances else "I am stupid for poisoning myself".
