sure !!, i because a fullstack php, web developer at age of 8, by 2 i was security pro too, profesional in around 8 diff programming languages ,
i actually think it was a lot easier to learn when i was young that now ! -i’m 31-
at such age you have all the time i the world, no commitments no worries, i remember i learned .net in 3 days !, and C in less than a week, now it may take me over 3 month just to get grasp on a new lang or framework.
