The number of opportunities in tech and the speed with which new ones arise can't be compared.
Look at the latest trend - AI. Not only did the initial boost come from openAI (US) its adoption by the biggest tech companies like Google, Microsoft, Nvidia, Apple etc - all American and all investing Billions.
But that's not even the most 'special' aspect of the US ( I'm sure SAP will jump in big into AI ) It's the hundreds of startups that are either starting or pivoting into the trend.
Now, this doesn't mean that this latest iteration of AI will be world-changing, it could turn out to be a complete bust. But it's this constant churn, the striving to be on the cutting edge, the rise and fall of dreams that makes the US 'special'.
