The next big world changing technology will be the technology, which will allow us to control devices through our thoughts. It's not the ability to control devices magically, but the ability to communicate without using your voice, that will impact our live the most.
How will this change us and our society? It's not improbable, that our ability to speak will degenerate with time. Babies won't hear the voice of their mother as they are developing in their wombs. They will probably already get an ear bone speaker, after they are born. So parents will be able to surveil their children better. Music with vocals will vanish, our way of thinking will change. Probably our own thought will sound like the vibrations we get from the speaker or we will only think in pictures or scenes or maybe we will see written sentences before our inner eyes.
What do you think, is this a realistic vision of the near future?
