If we're talking about the current generation as in Boruto's class, then yes, their potential speaks for itself.Their potentials (Current generation) speaks for themselves.
Dumb argument, and for more than one reason too. Naruto was, at the same time, a Genin and the world's strongest Shinobi. Therefore the exception, not the rule. Just like Obito. Not to mention Obito was not affiliated with the leaf at this point, so his official ranking doesn't really matter all that much, and while he didn't really train with the Mangekyou, he doesn't need to as, much like it did with Sasuke, the abilities came to him instinctually, he did train with Mokuton.That same Obito was still a chunin. Moreover, he didn't exactly trained with his Mangekyo Sharingan nor Mokuton.
