Google Instant Makes SEO Irrelevant →

Here’s what this means: no two people will see the same web. Once a single search would do the trick - and everyone saw the same results. That’s what made search engine optimization work. Now, with this, everyone is going to start tweaking their searches in real-time. The reason this is a game changer is feedback. When you get feedback, you change your behaviors. Think about it. When you push a door and it doesn’t open quickly, you push harder. When you try to drive a car up a hill and it doesn’t go as fast as you would like, you step on the gas. Feedback changes your behavior. Google Instant means no one will see the same web anymore, making optimizing it virtually impossible. Real-time feedback changes people’s behaviors.

Completely disagree.  Steve seems to forget here that SEO stands for “search engine optimization“…meaning you optimize for a specific search engine in mind based on what it allows you to do.  With Instant, it just means optimizing to rank only in the top 10 results that flash across the screen just got incredibly more important.  Not to mention, now trying to figure out how best to optimize for one-off letter keywords.
