This is silly. He's on his way to make a good point, but fails when his main points become 1) no math 2) focus on stories and language early on.
The good point he could have arrived at is to put less emphasis on things a child is not immediately acquiring. It would be like trying to force-feed mashed potatoes down a drinking straw. Perhaps sometimes it's math. Perhaps sometimes it's music.
Instead, he just says, stories and language are the important part! Leave math for later!
What a buffoon. He started with a bigger picture that ended with a close-minded detail.
To the original author, remind yourself that "not everyone is you." Kids can grow up to be scientists, artists, doctors, lawyers, even gasp mathematicians! And we all take different paths, even at a young age.
