This is a misapprehension. All the root servers (operated as a public 
service a range of organisations) tell you is where to find the DNS for 
(eg) all of .com or all of .co.uk

This information is pretty static :)

The next stage is to query the (eg) .com DNS server (run in this case by 
Verisign) to discover the location of the server with information about 
(eg) google.com

You then ask that server (run by google, or for smaller sites their 
hosting ISP) what it "knows about" the google.com domain, at which point 
you are no better off than having started your quest with your own ISP's 
DNS servers.
