I cinquecento milioni della Bégum

Verne often combines adventure with ideas about progress—I'm curious what motivated him to delve into the ethical implications of technological advancement here.

The vision of utopia in the book feels optimistic but also raises questions about control and morality. How did others interpret the social ideas Verne presented?

Verne's fascination with technology and future societies is clear, but I'm wondering whether he drew heavily from scientific theories or let his imagination run wild.
