My kids cousin at the age of 15? Was fast-tracked into some sort of accelerated learning program and at the moment is a uni student studying something to do with AI,I think she has been to some sort of Google summer school in silicone Valley, I will ask my son the full story, she is genius level IQ, just a skinny nondescript kid who was always in her room or on her laptop, I asked my kid why he wasn't a braniac like his cousin, he just said "my dad's side of the family cancelled the intelligence out".
