I think it's absurd to claim that every tech center is an offshoot of Silicon Valley. No one does this for other industries. Milan isn't considered an offshoot of Paris because it has a fashion industry. Chicago isn't considered an offshoot of New York because it has a financial industry. Similarly New York isn't considered an offshoot of London because it has a financial industry. Only for tech do we do this.
