Very happy to hear that not only is Apple still focused on making Screen Time better, they believe it’s a tool for children and adults alike. Here’s the exact quote from Cook:
I think that we've learned that some of our users are not happy with the amount of time that they invest in their device. So our response was let's figure out a way to help them. Let's put all of our energy into figuring out how to help them. And out of that pops parental controls because some people are more anxious about their kids. The truth is they should also be anxious about themselves. So we gave them Screen Time as well. And Screen Time is for kids and for adults. And there's no doubt that we will do more. There's no doubt we'll push forward for more.
