I’m not blaming anything. But it’s my theory that whatever consensus we enjoyed in the past was due to the information landscape of the time - where information was controlled and curated by a dozen or so centralized entities and their affiliates.
The internet though is mostly chaos. There are gatekeepers, e.g. Google, but they don’t curate much - using a blacklist approach rather than whitelist - and instead just organize the information making it findable.
Niche ideas get air time and now compete in the market place of ideas.
