Douglas Noel Adams (1952–2001) was the British bestselling author behind The Hitchhiker’s Guide to the Galaxy, celebrated for his groundbreaking fusion of science fiction and absurdist humor.

A Cambridge English literature graduate and former BBC Radio writer, Adams honed his satirical voice through work on Doctor Who and comedy troupes before creating his iconic intergalactic saga.

A pioneer in digital media, Adams co-founded h2g2, an early internet community, and advocated for environmental causes.

Why is The Hitchhiker’s Guide still relevant in 2025?

Its themes—AI, bureaucratic absurdity, and existential uncertainty—resonate in an era of rapid technological change. The rise of digital media and AI parallels theGuide’s fictional tech, making its satire feel eerily prescient.

How does The Hitchhiker’s Guide compare to Adams’ other works?
