Good thing there's more of a market than your mom, dad, and even your brother, or alternative search competitors like duckduckgo and others would be completely screwed.
Maybe the market of people that are significantly different from his/her mom is just too small to justify the significant investments needed to build a search engine.
Or said another way: If 99% are happy with Google, can the remaining 1% pay enough to finance "Google pro" ?
Is there an alternative search engine right now that is both good and not based heavily on an incumbent by a large tech company (ie: bing)? If not then the argument isn't disproved.
