Another reason to appreciate the line is seeing it for the way it fits a motif of the stories.

Take these scenes between Obi-Wan and Qui-Gon and later another with Obi-Wan and Anakin.

There’s a great deal of subtle implication and foreshadowing with each along with the poetic links between them. There’s even visual poetry as Anakin’s background is washed out and darker to signify further final steps to bring about the Empire while Obi-Wan’s is still colourful indicating his alliance with the Republic and democracy.

Anakin also often has the same ambitions as Dooku throughout Attack of the Clones. He promises he will become more powerful than any Jedi. Dooku claims he is.

Another thing to note about the Anakin and Padme exchange is exactly what jedi_bendu mentioned. It’s a different character later with Palpatine relying to Anakin a different motivation and way of seeing things to exploit him. Like when Obi-Wan tells him he’s wise and proud of him. Palpatine tells him he’s wise and strokes his ego with how he knows he’s always wanted a life of significance.

It’s a musical idea in a way. It’s a reoccurring motif within Star Wars that doesn’t get referenced nearly enough.

Personally my favourite is when Anakin tells Palpatine that Obi-Wan’s fate will be the same as ours. It has double meaning as they escape the Invisible Hand and all three end up dying on a Death Star.
