Well if you google "best toaster" then yes, Google will (and should) show you ads and sponsored posts and articles that have been seo-ed to death, because it's a meaningless search.
Google isn't in the business of assessing toasters' quality. Google is in the business of finding information relevant to your search.
But relevancy goes both ways: you need to search for something specific to find it.
"When will I die" will not point to anything interesting. "Pancreatic cancer symptoms" might.
