I got my start in programming basically via Minecraft. Multiplayer servers taught me DNS, ports, & bash... modding on Mac OSX & configuring a server to work with the same mod (Flan's Mod) taught me basic client-server principles... hell, even Buycraft fuelled my interest in Bitcoin and web development. I don't know if I'd even have been a serious developer at all if it wasn't for Minecraft.

And now kids have access to learning JS directly. This is 100x as powerful as learning how to web inspector pages. I look forward to watching my little cousins surpass me.
