During my first month at Intuit as Product Manger who coded, I pitched some ideas to my leader at the time. His feedback was to try to come up with ideas that were more practical. That pretty much sums it up. To credit Intuit, that leader is no longer with the company. The problem imo is this type of thinking shapes the way people think. On the flip side, VCs/Investors/Angels are only interested in the big ideas that sounds crazy that big companies reject.
