alt Hacker NewsThis is phenomenal, but my biggest question is (which is probably a more of a long-term one that comes from genuine curiosity/fascination, not doubt): does she use it/enjoy it? I'm so curious to see what happens over time. Does she learn the functions of these buttons, years before having words for what they're doing? Does she write some music? Does she grow up expecting things with knobs to be this interactive/creative? SO cool!
3-year-olds actually have quite a vocabulary, so they can certainly talk about what the knobs are doing, maybe just not as accurately as adults.
Regarding discovering functionality: The author mentions Montessori stuff, and the philosophy there is unguided discovery, "let them figure out by themselves". Not sure if that's how the author is planning to use this too, though.
