How Young Is Too Young to Learn to Code?

Christopher Mims:

When the American Academy of Pediatrics recommends that children under 2 spend exactly zero time in front of screens, what its members are concerned about is substitution — all the time those children aren’t spending acquiring new skills and language through one-on-one interaction.
Yet a new effort by researchers at MIT’s Lifelong Kindergarten group will attempt to create a programming environment suitable for toddlers. It’s hard to imagine that any but the most precocious children would be able to interact with Scratch Jr. before the age of two, but as Heather Chaplin reports for KQED, the new software will be aimed squarely at children who have barely learned their colors, much less how to read.
