As a user and fan of kagi, the problem with kagi is that it reveals how badly degraded the web is.

The vast majority of original content is now in one or another social network or on discord. News articles are an exception, though the news has its own problems. Some wikis still exist and are actively maintained, of course, but not a ton. If it's a topic that's academically studied you might find information in papers, but those have poor web visibility and are better located with specialty tools. LLMs seem to be quite good at locating papers, though.
