I have mixed feelings on this front. On one hand, a locked down computer encourages either extreme compliance (so no learning how to do new things) or encourages the kid to figure out a bypass which might be far worse than if they had an unmanaged computer to begin with.
Right now my oldest isn’t reading yet so I have controls primarily to enforce a time limit particularly for dopamine-heavy media apps, and to prevent how much she can accidentally do by clicking without a clue of what she’s clicking on and just clicking the colored button. I’ll play it by ear for how much control is necessary to ensure my kids can develop to be the best adults they can be. The one thing I’m not looking towards is that my oldest is only about 4 years away from the window where I’ll need to have “The Talk” with her, because many men in this world suck.
I love how cops take less training to arrest people than I took to professionally reset passwords
