Is there anything preventing new search engines? Except scale and servers. But what most of us want is just plain old ordinary search as it existed in 2006, so that is probably reproducible.
I know there are some other engines. Like DuckDuckGo, but just found out they are really just Bing.
Which I guess begs the question, if Google Sucks so bad, why doesn't Bing take over??? It isn't as bad, even if not great.
Edit: After reading more posts. Appears Kagi is doing this.
