Settings are not a design failure
No one mentioned video games settings?It's a solved problem there, have profiles : "Low", "Medium", "High", "Ultra High".They allow for a quick start, then as the user is more aware of the feature, the user can tune the predefined profiles themselves.You can have independent profiles for each independent feature : input profiles (keyboard/gamepads), graphics profiles, audio profiles, etcFor example, on a Google account, that would be a single drop down list with those options: "Private and no personalized experience" (everything turned off), "Private with personalized experience", "Public"
