i know that the devs make minecraft what they want, and i never claim command blocks were added for the younger players, maybe the devs made them as an idea to expand on the redstone capabilities in the game because they wanted to. what i mean by "They cater toward the growing younger audience" is that they are adding stuff that the younger players will find easier to use (the crafting guide booklet thing in the inventory, back in 2012 you had to guess or google on the wiki), not that that is a nessecerily a bad thing, but its just that older players may find it a bit strange that they add that now.
