I make this point regularly, but Ben Horowitz makes it more succinctly here: Technology adoption has flip-flopped.
20 years ago, the technology adoption curve generally conformed to the following order:
Government—specifically Defense and Intelligence organizations
Businesses—with large businesses going first and smaller businesses adopting later
Today things have completely reversed. The latest technology goes to consumers first, followed by small enterprises that behave like consumers, then larger ones, then the military. The stunning reversal is one of many profound side effects of broad scale Internet adoption.
