From Peter Lavers
Describing electrodes that can control people’s legs, Evan Peck says that such app-run systems will stop people being chained to their smartphones (11 April, p 18). But instead of attending to a navigation app, they will be on Facebook – or Periscope (11 April, p 19). Next, will joggers run on auto, watching a feed of a golden beach rolling by?
Imagine all this coordinated in the cloud so people don’t collide. What a risk to those not linked in, with people whizzing about them oblivious to their surrounds.
