With all due respect, Margaret, the value of early education is not in what you learn but in how it develops your brain and your ability to learn other things. From this perspective, coding is a excellent way of teaching logic and it's connection to real world applications. No one should confuse the teaching of coding skills with  a desire to produce armies of coders any more than they should confuse the teaching of cursive writing skills as an attempt to create armies of calligraphers.
