Google is not going to end the SEO. Google just want to make the quality sites stand in the top and low qualities in the last. Optimization is not going to end but the over optimization is not good according to Google's latest ranking and quality results producing algorithm (penguin).
SEO and linkbuilding will never stop even though much depends on Google. If Google will stop all kinds of SEO he will make a collapse of internet marketing from which Google itself greatly depends.
If SEO was a product then Google could attempt to stop it (but it would never be completely stopped) but as it is a service this means that SEO can't be stopped. It is very organic however and as it changes very quickly - quicker than Google can release updates - there are very few definitive rules which do not change. I think this is why some people, especially those new to the SEO world, feel that there is an end in sight. This certainly won't happen. SEO is a pure service and as long as there is a search engine, there will be SEO'ers.
