Well she (the oldest) already expressed an interest in coding, so that was part of it. But the general idea is to make the compute device into a creative tool a that be how she gets her start using it, rather than have it initially be just a social media interface.
When I was growing up I played a ton of video games. I got started coding because I wanted to make video games. But as soon as I started coding, the video games suddenly became less interesting. I’m hoping a similar transition occurs with her, and that would be the indication she is mature enough to use the device as a tool to achieve things rather than a passive input channel for media.
