Similarly, Google Maps has added features that make it a better map, and it's a great place to find what time a store closes and what their phone number is. But it's been essentially the same service, with iterative improvements, for years. There's a world of possible uses for that data beyond what we imagine when we think of a map.
Well, 98 percent of the market is not asking hard questions, so by dropping support, they are actually making their search product more tailored towards their market.
But it's still a tool to find relevant pages, not a tool to find answers. It's made some progress with the semantic web and knowledge graph, but that still provides basic facts about people, places, and things. At its core, it's still a portal. It's still just a much better version of Excite. Search today feels like it did in 1997: a "solved problem" ripe for disruption. Google has the talent, technology, and data to produce something an order of magnitude better.
Who downvoted this and why?
They seem to rely too much on site popularity, and not enough about quality of result, and god help you if you try to google a higher-level math problem.
Regarding the math problems: do you have an example of a query for which there's a good result on the internet, but Google doesn't return it?
