Fast forward to 2020- I don't know if this is a mere nostalgic bias that lives in my head, but I feel search engines (SEs) are not doing well what a SE should be. My defintion of a SE being- finding the most relevant search results in the ocean of the web.
Is it only me who thinks that the WWW ocean has had dramatic shifts, but SEs are still stuck in time? I personally find it difficult to point what exactly modern SEs are missing; but I do feel there's something terribly missing.
For example if I search for a movie, then a bit later I search for a person, the SE should 'know' that the person I'm looking for is an actor in that movie and give me relevant results, not completely unrelated random people. That's beyond trivial to do.
Also removing all 'popular' results from link farms and pop culture sites, excluding entire categories for example searching for a mythological figure should give me results from *.edu sites, not weird ass anime sites etc (and Googles filters no longer work properly so you can't drill down in queries anymore.)
I think the market is ripe for a new product that does what Google used to do before they abandoned their core competency (and DDG is a joke and doesn't count)
