But clearly if out of context someone said something like this:
"Clearly, the most obvious effect will be to greatly increase economic growth. The pace of advances in scientific research, biomedical innovation, manufacturing, supply chains, the efficiency of the financial system, and much more are almost guaranteed to lead to a much faster rate of economic growth. In Machines of Loving Grace, I suggest that a 10–20% sustained annual GDP growth rate may be possible."
I'd say that they were a snake oil salesman. All of my life experience says that there's no good reason to believe Dario's predictions here, but I'm taken in just as much as everyone else.
