What is the importance of Cambridge University in the book, The Humans: A Novel?

The campus of Cambridge University holds great significance, not just for the world at large - due to being one of the foremost centers for study and research in the world - but for the narrator personally.

This is where the original Andrew, before being taken, conducted his life's work and where he solved the elusive Riemann hypothesis. It is also the setting for the introduction of the narrator, while assuming the form of Andrew. He is spotted having his "breakdown" while running around the campus and then tries to return to normality all appearances when he goes back to work, when in fact he is trying to do the opposite and undo the work which has already been done.

The university is where he inevitably returns near the end of the novel, a sign of coming full circle.
