My child is in awe when he sees me use the Minecraft CLI. He was excited to start kindergarten specifically to learn to read and write enough to use the CLI. I'm hoping that will eventually be his entree into programming.

It does give me some hope that future generations will still use computers and not just tablets.

Language is kind of the way we have serialized our thoughts for communication and storage. CLI is probably the simplest way to implement that in a computer, but you could probably go quite far by providing a TTS/STT interface to a CLI.

I'm not saying that's what you should do with Minecraft, but it could be interesting to see how such an interface is usable.

Minecraft has taught our kids to write just for the search item interface. I just draw pictures with the words underneath for their favourites items and they copy them. A great carrot :)
