Many successful sales demonstrations have been made with defective products in the hands of competent persons who avoid demonstrating the features which don't work. Beautiful Xerox copies can be made from originals riddled with correction fluid. Silence is not acquiescence. Contrary to what you may have heard, silence of those present is not necessarily consent, even the reluctant variety. They simply may sit in stunned silence and figure ways of sabotaging the plan after they regain their composure.
Complexity attracts brilliance.
If you want brilliant people to work for you make it complex and demanding. Also, it's more intellectually rewarding. The greatest achievement is to use one's finest professional talents to accomplish something that didn't need to be done. Bad guys are replaced.
