Not directly related to degrowth but important I believe.
The big pitch for 5G is that the networks dramatically increase the speed of wireless communications. Not only will this innovation improve download speeds of high definition video, it will allow for virtually instantaneous connections between gadgets, thereby allowing for everything from virtual reality game-playing in real time, to driver-less cars with much better reaction times than humans (thereby reducing the likelihood of traffic fatalities) to surgeons in far-away communities able to conduct delicate surgeries using robotic mechanisms.  Intriguing as these technological novelties may be, they do come with a significant downside. A multitude of peer-reviewed scientific studies have pointed to the negative health impacts associated with the microwave radiation used in existing wireless networks. These include childhood cancer and behavioural effects, brain tumours, neurological effects including memory and cognitive deficits, male infertility effects, neuropsychiatric effects including depression, Electromagnetic Hypersensitivity, DNA damage, and malignant melanoma.
