If you get into it, it teaches quite a bit more than just basic problem solving and logistics.
Start building things with redstone and you can get quite deep into electronic circuits – building neat things that require you to learn about electronic logic gates, clocks, and timing (I have a working airlock & lava purge room that simultaneously opens a large lava moat around my base for killing creepers etc that congregate overnight, a working automatic harvesting room for mushrooms, and some other nifty things all running off redstone circuits)
Saw a video today of some 16 year old kid that built a working graphical calculator in the game – yes, with an actual pixel array for graphing functions – I had seen a number of binary calculators before, but this was the first time I had seen someone actually put one together with a real display.
