The Web used to be very information dense. It was built from the ground up by specialists and enthusiasts, educational and governmental institutions, and groups of like-minded individuals.
Then it became commercialized and commodified. Entire industries popped up to shovel mass-produced crap to masses of people through Amazon, Google, Facebook, etc. Forums became subreddits, blogs became tweets, homepages became Facebook profiles. And we’ve hyper-optimized the attention economy to keep us hooked on clickbait headlines and 30 second videos. The Web just bears no resemblance to what it was 10-20 years ago, and web search results are a reflection of that.
Maybe there’s a way to restore the Web of old. But that seems like putting the genie back in the bottle. More likely, IMO, something will eventually replace the Web, and Web search along with it.
