No, you don't seem to have been paying attention at all.
So, quick recap.
Judge used Sanji to gain an alliance with BM, because that's the only use he can think of for his one useless son. But then BM betrays them. As the Vinsmokes are about to be killed, Reiju tells us that she started to hate less her family name since she learned that Sanji grew up to be a kind person.
This already sets the stage for the siblings to side with Sanji EOS over Judge's ideology.
Then, Sanji saves his family and, when asked why by Judge, he explains that Luffy wouldn't want his crewmates to be petty and stuck in past grudges.
Sanji also claims that the Vinsmoke version of him is already dead, but this is the beginning of him accepting his family ties.
Later on, Judge declares in front of Luffy how much of a failure Sanji is, but Luffy can only see everything Judge is critiquing as Sanji's
strengths. This starts changing Sanji's own self-worth.
At this point, Sanji is still a tsundere towards the Vinsmokes and after revealing that he was given a raid suit by his brother, he claims that he'll never use such cheap tricks as "science".
Sanji's view is immature, and the SHs tell him so. On the one hand, Luffy and Chopper are hyped by the possibilities within the suit, while on the other Nami teaches Sanji to accept that science can do wonderful things.
This begins changing Sanji's opinion. Against Page One, he puts aside his pride to be as helpful as possible. He still rejects the Germa heritage, but the suit's pervy abilities already seduce him.
He even admits that his father's science has
revitalized his dream!
And the fictional myth of Sora is immediately mentioned!
Then, just as Sanji was getting cozy to the idea of becoming "Stealth Black", in a chapter titled
"Warrior of Science" (how much obvious can this be?), after being tricked by Queen into thinking that the raid is turning him into someone who'd hurt a woman, Sanji destroys the suit, not wanting to become controlled by Judge's tech.
Once more he rejects Germa, yet he is aware that
his enhancements have been awakened and he'll never be the same again.
Enhancements that include durability, healing, super strength,
and an icy heart. But Sanji doesn't have an icy heart. That's what sets him apart from his siblings. Now, after the raid suit has activated his genes, Sanji has everything his siblings have,
and more--he maintained his humanity. His heart. His soul. His passions. That's what puts him above Judge's "successful" creations.
Queen wants to show the superiority of his technology over Judge's (because the siblings are still tech: they are genetic modifications, but they're still manmade improvements to the human biological baseline), which is when Sanji's heart changes once more. Having realized Queen's deception with the prostitute, Sanji can regain his identity, knowing that the tech isn't controlling him.
He is in control.
And there you have it. Sanji finally accepts everything Judge gave him, and combines it with his own will to surpass his engineering and become stronger than Judge could've ever imagined.
This is when the fight against Queen ends. When Sanji finally
integrates his Germa lineage into his own identity. When he lets his flames burn as bright as his will and modified body can allow him.
Because there's a reason why Sanji's element is fire. Fire in OP represents passion, represents will, ambition.
And Sanji now has outgrown his ego enough to one day accomplish what BM wanted to do:
Use Germa's science for good.
That's how Sanji will redeem his family's past. This is the path forward, using the product of centuries of experiments and eugenic ideology to help the future Pirate King liberate the world!
This is what you can't seem to comprehend. The raid suit was not just
another power-up. It was a means to activate Sanji's genetic baggage, and therefore a jumpstart for his final character development, to get him where he needs to be by EOS: Vinsmoke Sanji, proud Germa leader, and left wing of the PK.
The genes, the suit, the exoskeleton are just half of the equation. The heart is the other half.
While the former half has carried much of the narrative from WCI until Wano, in Egghead Oda started focusing
again (because that's always been Sanji's core identity trait) on his passions.
Which is why, in an arc in which the greatest scientist in the world acknowledges the existence of the soul, in an arc in which a cyborg ignores his death switch to save his daughter, in an arc in which a clone overwrites her orders because of the love that her original self proved for Luffy, Sanji starts blabbering about the Power of Love.
Being an augmented human is no longer a problem for him.
Being a Germa product is no longer a problem.
Sanji has overcome his identity crisis. He can now go back to being himself, back to expressing his passions.
That's Sanji's future:
tech + love
That's what makes the perfect augmented human. And that's why the siblings are Judge's failures, and not Sanji. Because Judge removed their emotions, effectively
neutering half of their potential.
EOS, Sanji will push his genes and his passions to the max, showing the entire world what the Germa lineage is capable of. It's not a coincidence that Germa's eagle emblem resembles Black Stealth's hairstyle.
During the Final War, there will be those countries who will follow Luffy because he's helped them (Alabasta, Drum, Amazon Lily, FMI, etc.) and those others who are tied to a specific Strawhat.
And then there will be Germa, which will show up under the pretext of claiming back their territory, but in reality they'll be there for Sanji, and Sanji will once more get out of his way to save them and even lead them, because Sanji won't hold onto the grudge anymore.
Warrior of Science Sanji is inevitable, though that could only be half of it. I wouldn't be surprised if Oda makes him a
Warrior of Science and Love to prove his point that science can improve human lives, but it is only a crutch when divorced from the emotional side of man.
You don't need to use Bonney as an example since, technically, DF users are enhanced humans--or at the very least, all zoans, logias, and the paramecias who change your body. DFs are technology, not magic. That's why VP can replicate them. And they do enhance a baseline human, which is why, again, VP describes them as potential human evolutions and why the one who eats a specific fruit is called a "x man", rubber-man, fire-man, string-man, etc. The DF adds something
more to the human biology.
IMO, current Nika's sword and shield are allegorical.
Zoro is Luffy's sword.
Sanji is Luffy's shield.
EOS, this will become clear, as Zoro achieves the greatest attack power in the series (thus gaining the WSS title), while Sanji develops his exoskeleton to an almost unpenetrable level, far surpassing the Lunarians (which are currently the characters with the best defense in the series, and to whom Sanji has been compared twice by Queen).
