I read the question as innovation around mobile. N. America is behind other parts of the world with 5G adoption.
Very interesting question. When I started my career with Motorola, the balance was strongly in the US, because Motorola was the number one player in the world. Then when the first two digital phones came, the balance of power shifted to Europe, with Nokia and Ericsson leading the charge. Later on, when the iPhone came, the whole thing shifted back to the US to the west coast. So it was the US Midwest, then it went to Central Europe and then it was back in the US where it is today. Apple and Google also helped democratize the whole application space through the app stores and that enables anyone--in India, China or Japan--to create applications right on top of their platforms to the benefit of the entire ecosystem. I think it is very difficult to dislodge such a powerful ecosystem and the network effect that Apple and Google have today.
