The Kantian notion of appearances ultimately being the ground of things does point us in the direction of the things themselves (perhaps the ultimate goal, answering Jacobi's complaint), and it also makes us aware of what other people are doing with their truth claims. The world has always been overlaid by shared views of the world composed of gossip, misdirection and mistake -- the risk of present error might be that in the attempt to ground these perceptions in the way that things actually are, one of these systems needs to acquire extraordinary mechanisms of perception and corresponding influence so that truth can govern the world. And the things going on now quietly, behind the scenes with certain California data-based companies, when combined with AI management, might actually being such a scheme into existence, and more troublingly, action.
To which, I can only reply, with a bit of Kant in my rucksack -- go back to Kant!
