I agree that the major platforms have the tools to filter it out. I disagree that those tools are doing that. The primary intent of algos is around engagement, not quality content. We might be able to say the end result is similar (users are engaging on the internet when they wouldn't otherwise if they were getting garbage), but I don't think it's the same. Users aren't being spoon fed high quality content for the brain. They're getting addictive, engagement content to keep them parked on their phones. If content was nutrition for the brain, algos are feeding people candy instead of vegetables. Maybe it's not actual garbage, but most people are not "eating well" with the current approach to content curation by algos.
