One, or even zero person companies have been a talking point for a while, and I think we will start to see them in a serious way by 2030.

We're in this strange world right now that has invented intelligence as a new commodity, but we don't have the right tools to utilize it.
We have oil, but no cars.
I think building these tools is what will change the world the most in the next few years.
