Fortunately, he is safe with his real family, not with a bunch of attention-seeking Miami Cubans.
He'll probably grow up to be an intelligent, well-rounded human being, not just because of the media attention his plight attracted but because Cuba has one of the highest standards of literacy in the world.
So he can realistically expect to receive a better education there than he would have got in the Miami public school he would otherwise have stagnated in. Or (shudder at the thought) that mob could have tried to homeschool him.
