reasons that corporations ruined S & T, not the other way arround. Why so many seeming-great S& T discoveries failed?? Because the greed of the managment! Why the greed? Because it is perceived to be easy money to earn in managment. The managment deviated from the pursuit of new frontiers in S & T by following the cues from the "Expectations" of Wall Street!
The purpose of S&T is not to earn money or to provide great ROI. Before a discovery is made, no one can be sure of its value or "return."
