TLDR: RFK's suggestion of forcing everyone to use "wearable" technology only has one possible downside - it could negatively effect our mental health. Don't even worry about some of the other predictions about "digital dictatorships," suggesting that wearable tech could be used to monitor your biometric data and punish those not loyal enough to the ruling class... no, there's zero threat of this tech being used by intelligence agencies for anything nefarious. The ONLY threat is you might get depressed if you aren't losing weight fast enough.
