If you look at Fortune's list of unicorns, 3 of the top 10 are in Beijing. As they build, they're strengthening the founder/techie/investor ecosystem in the city even further.
Just having the talent, a silicon valley doesn't make. Its about the culture of collaboration and openness.

Automotive and related tech is quite small even with Tesla in the bay area. The number of automotive technology jobs is quite small. Automation technology from cars is picking up, but I doubt the number of jobs is very high in comparison to Detroit, Stuttgart, or Nagoya
There are a lot more aerospace outside of Silicon Valley with Aerobus and Boeing having little presence in California.
Google is #3 in cloud technology compared to Seattle/Redmond with AWS and Azure with significant marketshare advantage.
Amazon is 45% marketshare in US for online commerce. Logistics technology for them is mainly built in Seattle and Boston. Not much for Amazon going on in Silicon Valley. Alexa not made in Silicon Valley.
I'm still quite surprised people still believe Silicon Valley + SF lead in technology.
I can walk around and pay for everything with my cellphone nowadays in China, but can't really do that in Bay Area.
Is this really that interesting though? Tell me when they have self-driving cars that are affordable enough for ride sharing.
As for self-driving cars, Chinese companies like Baidu are not unlike Google, and they are investing/researching heavily in these fields. The only twist is that self-driving in China would be a lot harder to solve because the roads are a lot messy there :) At the same time, many of these companies directly invests in US companies as well
Because it's not a technical problem. Nobody cares about the ability to pay with their phone in the US when a credit card works so well and doesn't have a battery that dies.
Android and Apple pay work perfectly fine but almost nobody in my tech circles feels the urge to use them, let alone normal citizens. The credit card infrastructure in the US is so prevalent and reliable that there needs to be some serious perks to unseat the dominance.
