Because there are actually multiple "arenas of discourse" and people will simply switch the "marketplace" they're using.
It's technocratic hubris to think that there is just a single such arena and that all the others are illegitimate/dangerous.

IMO "truth" is distraction here because what is at stake here are people's values, not their understanding of math and physics. When people worry about "post-truth", they're worried about liberal values no longer being the unquestioned default. It is absolutely a marketplace, and if people switching marketplaces en-masse makes it harder to launch rockets and develop vaccines, then it probably means those activities are making people net unhappy. People are a lot smarter than we give them credit for, even the dumb ones.
We are (well, I am, and TFA is) not talking about epistemology so much as the public's inability to engage with epistemological problems on systemic scales. Instead the limits of human psychology control how we as a society respond to these issues. Your argument is a distraction that remains uncontextualized within the conversation it finds itself in.
People are not dumb animals but you won't be able to engage anyone toward a solution on the basis of an argument about how they just need to understand more about epistemology. That's the kind of thing that people can only internalize via empirical means.
At this point it feels like you're being deliberately obtuse. I've been quite clear about the primacy of human psychological limits as the main aspect of the argument and you simply refuse to engage with this point. You haven't been very good about adding to the conversation, only diverting it.
The public's inability? What about everyone's inability. No one deals well with epistemological problems on a systematic scale, not even the technologists who delude themselves into thinking that they're driving anything.
I am exactly talking about psychological limits. The difference is that I don't think the psychological limits of the creators are any different from those of the users. If anything, I think the creators are more psychologically limited than the users. This is because the creators need to explain to themselves why they are creating the thing - everyone else just puts up with it. When you say ppl will either be duped or completely check out of discourse, don't forget about yourself.
Also, of course I didn't read the article....
