The era of dominance is shrinking. IBM dominated tech longer than Microsoft did, and Google's period of dominance will be even shorter. As with IBM and Microsoft, a great and wealthy company will remain (after a painful period of post-dominance restructuring). But during the period of dominance, it is hard to imagine anything else. Vast fortunes are lost in attempting a head-on challenge (whether they are search engine challengers to Google, operating system challengers to Microsoft, etc.), and disruption never happens that way. Google has no problem adding enough semantic smarts to see any challenger off. It's the Real-Time Web that will unseat Google. This idea has been percolating for a while, but it took a plane landing in the Hudson River to make it obvious.
