Yes, I curated their content, but I do believe too much of any one thing is bad. We didn't get a phone until I was a 11 or 12, not because of beliefs, but money. I became a real bookworm to the detriment of getting outside and exercising for a few years. I try to mix everything up a bit. I also believe in a diversity of intelligence. Each one of my children has a different angle on intelligence. It's amazing to see the different manifestations even within the same family. I think what we think is good content evolves every 5 to 10 years; a study comes out refuting a solidly held confidence in a technique or manner of raising children. I think if you keep it diverse, and try and challenge yourself, your kids and you gain tremendously.
