Martin Heidegger In case it helps anyone, here's some more context for my interpretation of H:
Language is not merely a tool which man possesses alongside many others; language first grants the possibility of standing in the midst of the openness of beings. Only where there is language, is there world, that is, the constantly changing cycle of decision and work, of action and responsibility, but also of arbitrariness and turmoil, decay and confusion.

The one as that which forms everyday being-with-one-another...constitutes what we call the public in the strict sense of the word. It implies that the world is always already primarily given as the common world. It is not the case on the one hand there are first individual subjects which at any given time have their own world; and that the task would then arise of putting together, by virtue of some sort of arrangement, the various particular worlds of individuals and of agreeing how one would have a common world. This is how philosophers imagine these things when they ask about the constitution of the inter-subjective world. We say instead that the first thing that is given is the common world -- the one.
Then this is about the gossip we are thrown into, the gossip we mostly are. We are Poloniusbots with the potential to switch into Hamletbot mode if we can hear our superficiality. Polonius must realize that he's mostly a bot, suffer the terror of never having been, of having been lived by an anyone who was no one at all, a mere echo of what one says what one says. I claim that if you don't feel how thrown you are then you can't understand what's crucial in Heidegger.
What is talked about is understood only approximately and superficially. One means the same thing because it is in the same averageness that we have a common understanding of what is said.” “Publicness ” does not get to "the heart of the matter," because it is insensitive to every difference of level and genuineness.”
Idle talk is the possibility of understanding everything without any previous appropriation of the matter. Idle talk, which everyone can snatch up, not only divests us of the task of genuine understanding, but develops an indifferent intelligibility for which nothing is closed off any longer. Discourse, which belongs to the essential constitution of being of Dasein, and also constitutes its disclosedness, has the possibility of becoming idle talk, and as such of not really keeping being-in-the-world open in an articulated understanding, but of closing it off and covering over inner worldly beings. “ “ Ontologically, this means that when Da-sein maintains itself in idle talk, it is-as being-in-the-world-cut off from the primary and primordially genuine relations of being toward the world, toward Mitda-sein, toward being-in itself.”
Idle talk conceals simply because of its characteristic failure to address things in an originary way [urspriinglichen Ansprechens]. It obscures the true appearance of the world and the events in it by instituting a dominant view [herrschende Ansicht].”“Usually and for the most part the ontic mode of being-in (discoverture) is concealment [Verdeckung]. Interpretedness, which is speech encrusted by idle talk, draws any given Dasein into 'one's' way of being. But existence in the 'one' now entails the concealment and marginalization of the genuine self [eigentlichen Selbst]. Not only has each particular given itself over to 'one', 'one' blocks Dasein's access to the state it finds itself in [Befindlichkeit].
One is a bot.
