You mention options in passing, but it is to me the root of the problem: Google hates giving up control. Control means ad revenue. So we could have options that would make search extremely efficient for most users, but that would presumably be very hard to monetize in comparison. So we have no options, and everyone gets mediocre to bad results.
Since everyone I know in tech laments Google's decline into uselessness, I'm assuming this is not a sustainable strategy.
Everything I've heard from people I know at Google suggests otherwise. Most searches for most people ... work. I too struggle to have google work in specific research cases, and I would like more power-user toggles, but basic searches like "$celeberty_name photos" or "$my_kids_school calendar" or "pizza places near me" just sorta work.
Hard to know anything for sure since results are "tailored". But Google used to be excellent for technical searches, whereas now it is unhelpful at the best of times. I'm guessing this isn't counted in "most searches gor most people".
