You've got the definition of a prodigy all wrong. A prodigy is not someone who is invincible and Kishimoto has proven that with the confirmed prodigies/genuis like Sasuke, Kakashi, Itachi, Madara, Neji, Lee, and etc. Boruto did not get the device out of feeling insecure of his abilities.
i did not ever say Bolt was supposed to be invincible. I don't know you could have possibly got that out of my post.
The spoilers said he was tricked into using the device by a scientist who was trying use Boruto as a marketing tatic. Boruto even was reluctant to use the device during round 1 as said by spoilers.
it also said Naruto had expressly forbade the use of that guy's technology. There are a set of spoilers that says Bolt used it more than the one incident in which he finally got caught, so he wasn't that reluctant to use it if that allegation is true.
It has nothing to do with being a true prodigy because last time I checked neither of those character besides Neji and Lee were using their purely own blood sweat hard earned abilities all by themselves. So how are they still holding the title of prodigies when they too have powers that aren't soley theirs?
did Lee or Neji use a bracelet that allowed to perform techniques outside their own skill set? No. The bottom line is that there is absolutely no need for prodigies to cheat if they are already more talented than others. It's like hearing a 7 yr old kid that can do math at a college lvl had to cheat their way through addition and subtraction problems. For someone who has been hyped as a prodigy, the CE shouldn't have been any more than a walk in the park to them.
I say he's the most talented and added as far as we know because the only gen kid confirmed a prodigy and the only with the most feats. I think a kid who managed to accomplish what Minato and Kakashi failed to do with no effort what's so ever can be said the most talented when no other kid hasn't gotten that hype.
Kakashi was called one too, and it turns out Gai was better than Kakashi for who knows how many yrs. With all of the effort to downplay and berate Salad, she still has what some may consider to be a better feat in the Gaiden, and she needed nobody's technology to pull any of it off.
