Eh I disagree. I approach it from a different perspective. But please, if you think that organic SEO is dead, then by all means don't worry about it so I can take all the real estate in that area
Let's use the example of HD Monitor that you mentioned. We have your standard PPC ads on the top and right -- no changes there. We also have the shopping results and related search above the organic listings. While they take up space and push the organic listings down, they're an essential element on the page (and great for users!). Let's say I do SEO for Amazon -- you better believe it's my responsibility to make sure Amazon is both in the shopping results and related searches AS WELL AS the PPC ads and organic listings. SEO is about page real estate and the better positioned I am in all aspects, the likelier I am to get a click through.
To generalize and say that SEO is all about organic SEO, whatever that truly means, is to completely miss the point of what SEO is about. Google is always trying to make things better for the user -- so if you're an SEO, you better adapt to those changes and make sure your business is positioned well in all sectors.
But looking forward, who's not to say that the related searches and shopping results won't become what you deem "organic" if they're naturally populated based upon effective optimization on the web?
