Will Google/yahoo/bing destroy SEO ?

[lorerush]

Now why have i asked this question .?
the answer is simple ..
if google is so called "god of internet"
then SEO is a challange for the Google .
the only option that google has is to make their searching techniques more precise and accurate . Do u think google is sitting idle and doing nothing ..?
What if they find a technique to track SEO's and ban them .. or find a technique to give very precise results irrespective of implementing all SEO techniques ...
Technology has always Surprised People.
begin an SEO i am a bit concerned about it ... would also like know ur views and ideas to overcome it , if at all this happens :-)
