OGU I think they knew that Boruto would never rise to the acclaim that is Naruto. It's unlikely despite peace that ninja like Naruto and Sasuke would weaken so greatly in such a short amount of time so as to create a path for the next generation to rise as the final bosses of their village. Hence why they removed them both to allow the children time to develop through their own hardships. For me, I still think Naruto has more in the tank. It's likely just nostalgia speaking.
There have been plenty of real-world examples where the next generation of a family does not surpass the generation before it. And I'm not saying that as a Naruto fan, I'm saying it as a statement of fact. That's said, the hope is always that the new generation WILL become stronger than a generation before. I JUST HATE that it seems like in order for Boruto to surpass Naruto he had to be nerfed. There is no reason why Naruto in his 30s would naturally weakened so much that his son would be able to surpass him so quickly. So of course, let's create storylines that force him into a state of weakness. Same for Sasuke. I just don't like the decision to make them weaker because Boruto only surpasses Naruto in his CURRENT state. I think Boruto deserves better.
