The "Men In Black 3" star said his two kids with wife Jada Pinkett Smith understand the fame game well but he knows they will suffer from things that will hurt their self-esteem in the future.
"Do I worry about Willow and Jaden? No, they were born into that world. They're on the internet all the time, so they know the game. They know where to go, what to say. They're far more savvy.
"Of course there are going to be things that are hurtful and self-esteem issues, like we all have, but I grew up in a neighbourhood where I saw a guy get shot and take nine bullets to the chest, so Hollywood is a far safer experience than where I grew up," he said.
Smith, 43, has been spending more time at home recently as he has been working in production rather than in front of the camera, but he said his family is now ready for him to leave the house.
"Willow's doing her music and whipping her hair, Jaden's got a TV show. And daddy's been sort of producing at home. But everyone's really ready for daddy to go back to work now."
