Is 'predictive search' about to make SEO obsolete?

Rachel Pasqua blogs at Search Engine Watch: 

Call it what you like – predictive, unified, aggregated – Google Now is a glimpse at the seamlessly personalized, contextually complex, nascent future of search. 

Picture a business traveler in a foreign city for work with Google Now installed on her smartphone – or, even more likely, her Google Glasses. 

The viewfinder of her glasses with built-in Now functionality will guide her seamlessly throughout her day in a unfamiliar locale, presenting visual maps and directions to her calendared meetings, flashing safety alerts, translating price tags into more familiar currency and presenting her with real-time tips on local business etiquette – all without her having to do more than blink. 

She'll be able to text, email, and post to Google simply by speaking and gazing at her surroundings as she goes about her day, more efficiently than if she had a real human assistant in tow. 

This is a blue skies vision of what's likely to come but it's fair to say that Now is truly the first virtual personal assistant worthy of the title.
