The next Trillion company

Today, among a causal chat, one of my colleague shows me her recent experience in Shengzhen, China. robots are now severing customer/Tenant now. I searched a bit, and found some reports around like this one.

I just moved to US for several months and still amazed how fast things are going on in China. everything is evolving so fast, especially in the tech areas.

20 years ago, everyone need Windows, Microsoft becomes a Trillion company. 10 years ago, everyone need a cellphone, Apple reborn from the dead. who will be the next?
