>>120530331) The wireless aspects of the devices will cause neurological changes, altered development, brain damage outright, impaired fertility, hormonal and endocrine changes, DNA damage, etc.
2) The blue light and flicker (is this still a thing?) from the screens will destroy the photoreceptors in their eyes, suppress melatonin synthesis, alter their skin flora, and ultimately lead again, to cancers, impaired immunity, and degenerative disease.
3) Their ability to navigate the real world will naturally be impaired as they fail to properly develop motor skills, their own mental tools like visualization and arithmetic, and essentially the device will become part of their mind. Not in addition to their mind, it will extend and supplant, leaving the user in large part dependent.
4) Growing up on the internet and experiencing yourself through a representation in a virtual space, that is decoupling body, mind, and persistence of identity, will lead to narcissism and psychopathy. Without true access to self, there can be no other. Interacting with confabulated and contrived avatars of other people doing the same will render you a muddled caricature. Empathy will cease entirely. On what basis shall it exist? It cannot. Children naturally develop empathy, I think, but it can be pruned and conditioned out later through deprivation, conflicting demands, and so forth.
A lot of people are very excited to be here and now, but I have to see the future as bleak. We won't stop until our own bodies have been made into transceivers so we can all be connected as parts of a grand God-like being. And then we... what, manage population growth, embrace automation and AI central planning economies, live in virtual worlds, shed our bodies (borg), or having conquered all natural obstacles we either fizzle out in apathy, or we manufacture new problems to fight over until we destroy ourselves. Most likely the former.
Roads that lead nowhere. There is a flaw in our core design.
