Reversing option.

Hello everyone !so there is a thing in my head going for long which is that we have so many options to choose from and like if you go to Amazon and search for something you will find millions of option and any other category of apps like food, hotel etc.

But I think we just go through options to find out best stuff in our budegt to buy and by the best I mean and define is by the product which is highly rated by other consumers and price that's it so why do we have to go through option at all in first place why can't we just type for eg best vaccum cleaner in 200$ dollar range and the only result is showed that we can buy , i know most of you will say about filters that are available but I am talking about AI and neural engine which just streamline our buying habbits and fasten the process of buying leading to reduction of time chossing stuff .

Please comment , help me fix the bug in my head
