World run by telco

I always wonder how the world can be run by global companies who rely on such terrible tool of communication such as the teleconference.

Everytime I am doing telco I hear only around 50 percent people in the room. And even when the volume is right there is either too much noise or quality of signal is failing.

Noone ever says I dont hear nothing because everyone is reading emails on portable devices or wiping their asses on WC.
