You say it as if criticizing a joke is obviously something not to do for some reason? It is not like the joke does not imply something the author tries to say, otherwise it would not be on the front page. That aside, you overstate the difference to what we have today dramatically. Your browser history is already that and look at what controls firefox built on top to let you manage it. You can pause it, limit it, exclude pages etc. An adversary can root your pc and enable key logger and screen recording if they can break into an encrypted database, the delta to what adversaries already have is not that big, but the unlock for users and agents is quite big.
