Randomness works well in search sometimes better than humans.
It turns out a human being in two, three or four hours can build a search result that's much better than Google, Yahoo or Ask.
In comparison, Google is brilliant because it uses an algorithm that ranks Web pages by the number of links to them, with those links themselves valued by the number of links to their page of origin.
I would say the larger the pool you have to select from, the more likely you are to find the most compatible person for you if you have the right algorithms working on your behalf.
Yandex originated from a company called Arkadia, which created two search programs under the DOS operating system in 1990.
Spotify, Tidal, and even YouTube, to a degree, are vast and rich troves of music, but they primarily function as search engines organized by algorithms. You typically have to know what you're looking for in order to find it.
Without your data, Google couldn't pursue the dream of trying to figure out what you're really thinking when you're asking a question, of trying to discern, from the imprecision of your language, the exact answer you're looking for.
The story of Google is just when everyone concluded that a search engine would never make any money, everyone backed out of it, and Google walked into that vacuum and dominated.
When we miss with all the metadata collection we've had, the San Bernardino couple and the Tsarnaev brothers, what that suggests to me is that we are using the wrong algorithms to search through all this data.
