Meucci was a inventor (invented the phone) and Olivetti was a visionary enterpreneur (his company invented the first programmabke desktop computer, then illegally copied by HP).
The market was unable to understand the utility provided, because it simply does not work as in the classical economy models.
There is an annoying feature of the market called information asymmetry that makes often impossible to understand (and thus pay for) what provide value. It's a slightly advanced topic in microeconomics (that in fact, I studied at the University, in the course of Political Science, decades ago).
But while I'm trying to provide you with a different perspective (and actually a well informed one on the topic) it seems that you feel insulted.
So there is no need to continue this convesation: keep thinking that I confirmed your opinion if it make you feel better than understanding what I actually wrote..
