Don’t let Big Tech inside your head
Many of us blithely allow any old app to track what we’re up to, says Camilla Cavendish in the FT, despite that “vague, creeping feeling” our electronic devices are working against us. But “we need to wise up”, because a new challenge is coming: “how to protect our brain data”. Investment is pouring into “neurotechnology”, which can “record and analyse electrical impulses” from our minds. Brain-computer interfaces have enormous potential benefits, such as helping paralysed people communicate freely or “aiding the recovery of stroke patients”. Gamers could use them to control on-screen characters.
