You can say "learn to read" right now
But don't become a coward and run away when Luffy doesn't beat Saturn
I still stand on my train and that hasn't changed since November of last year
Regardless of how close we are to the end of the arc, you should keep in mind that the whole premise of the arc revolves around Saturn
Saturn is the reason Kuma turned into a robot, that Ginny died, that Bonney suffered, that all of the Gorosei are in Egghead, that Vegapunk died (Kizaru finished him off though), and the list is long
Without Saturn, you have no Egghead arc, you have no Bonney interacting with Vegapunk and the list is long
Saturn is the reason Bonney got her fruit "juice", the reason why Bonney can imitate Nika, the reason why Bonney suffered, the reason why Kuma is still immobile
The whole Egghead arc revolves around Saturn
There is no better conclusion to this arc than Saturn going down, this is the perfect climax one can wish for this arc, whether it is by Luffy alone or by Luffy + Bonney
Why postpone this to a later moment when you can bring him down now and perfectly conclude the arc by his defeat? The reason why this arc started in the first place?
The arc may still end without anyone being defeated though, don't get me wrong but I'll stand my ground until the arc finishes, then we will see
