Why must we replace phones so often? Why are they hard to repair? Can they truly be recycled? Where are digital data stored? While we picture an intangible world of waves and satellites, Hugo Clément reveals a very different reality. France hosts over 250 data centres, consuming twice as much energy as all urban lighting combined. Data travel via under‑sea cables, not satellites. Production relies on a massive nickel mine in New Caledonia, heavily impacting nature. Activists push for reparable phones and are prepared to sue major manufacturers.
