Why people think, that Brout will surpass his dad.

[Pukkake Pokayo]

The point went over your head. You took the highest character in the series and asked who surpassed her. Your logic is flawed because Kaguya isn't part of the generations of humans. She's an alien from another world.
You're talking about one species surpassing the other. I'm talking about humans surpassing humans. Do you know what generation is in Naruto? If you do you would know since the start of Konoha, every generation has surpassed the previous.

I thought each generation got weaker due to diluted genes, with a few exceptions until Hago intervened again. I guess Naruto &Sauce could've passed Hashi & Mads.

Gonna take a lot of BS power ups for him to catch up.

Without Kyuubi, he can.

No because Naruto has rikudo sage mode.

He may surpass Part1 Naruto with a technique powerful than Rasengan.
