Introduction to tech should still be age appropriate and have constraints. That's different from avoiding it completely. Some apps should be limited and it should be pointed out why to the kid so they understand the dangers.

We know there are problems with ads, privacy, and subtle ways our "free" apps try to gain our attention. Kids are more capable than you may realize of understanding those issues too, and the sooner you work WITH them to learn those issues and how to counter them, the better.

Having said that, if a parent doesn't have a healthy relationship with tech themselves, they're going to have a hard time teaching their children.
