What would a new HST look like? Gonzo style journalism kinda already peaked in the 2010s with the wave of blogging and new media like Vice magazine.
HST was revolutionary because he broke the norms of journalism at the time while still making a coherent point. Nowadays journalism is plain broken, the norms are in tatters and the people that would be exposed don't give a shit and feel no shame for the awful things they do. No wonder HST offed himself.
