Here's my take on "child prodigies"
I once heard of a 6 year old chinese girl playing the classical guitar that could rival Segovia. I figured by the time she's an adult she'll be famous. She was, at the time I heard of her, already 26 years old...never heard of her, she never did shit in the music industry.
This kid is jacked no doubt. Does that mean anything? No. Ronnie Coleman did not look like that at age 6 and he became the greatest ever.
Being a child prodigy in my book means nothing.
