Acknowledging that “building it” is not enough, the text stresses that a strong distribution plan is essential for market penetration and success. Finally, Thiel advocates that technology should be developed to complement human abilities, rather than substitute them, as seen in companies that combine software with human analysis to solve complex challenges. ...
