I really can't tell if we are headed towards a "1984" dystopia, a "Brave New World" dystopia, a Black Mirror "Nosedive" dystopia, or now a "GATTACA" dystopia. It seems like we're headed to a horrible hybrid combination of all of the above.
I don't mean this in a seriously snarky tone, but: What you're saying has been said by every generation which experienced great leaps in technology. Why is this wave of technology, one less transformative than the invention of the printing press or transistor or nuclear bombs (none of which lead to ruin), going to be the one that leads to a dystopia?
But now our technology is becoming an approximation of the human mind. Our sensors are ever present, there is not even the illusion of privacy. Our algorithms get better everyday on predicting who you are and what you want, just by the friends you keep.
