With Nature reporting that quadriplegics can check e-mail and play computer games by the power of thought thanks to a BrainGate chip, the scary prospect of a human internet – the networked brain or Humanet – must be upon us. Okay, so it’s all pretty basic now, but so is all technology at the start. Networking human brains might enable us to share memories, skills and knowledge effortlessly. A wired new born (or even foetus) would have immediate access to many lifetimes of experience and those online might never be sure of what they’d experienced for themselves and what had been felt by others. Perhaps they wouldn’t even care. Perhaps those on the Humanet would have a single shared consciousness. And what if other animals were connected to the same network?
