Calling the article "bogus" is rather... bogus. It is a concept piece. On the other hand, innovation doesn't grow out of factual admiration, only out of mutual stimulation.
I agree: We ARE taught to be too diplomatic and polite, and when we're not, we tend to be abrasive rather than constructive. Public officials have forgotten how to stimulate effective debate that results in effective solutions, and as a society we tend to live obliviously in our comfort zone and neglect to relate to surrounding reality.
Tomorrow's success will be found beyond the borders of today's knowledge. We'll only get to the innovations of tomorrow if we open our minds to learn something new and commingle our hopes and dreams and creative ideas into a synergy of new potential.
But we can't improve on today without some constructive interaction between opposing points of view. Collaboration isn't only for like-minded participants; that results in inertia. Rather, effective collaboration requires mutual stimulation that produces AHA moments that take thought into new trajectories of possibility. Deprecating anyone's input is counterproductive to the desired result. The point of collaboration is to create new potential.
